Shoulder pain is a common problem with a number of different causes. It's often a symptom of another problem.
There are a number of reasons why you might be experiencing shoulder pain, which include:
In some cases, pain in the shoulder isn't caused by a problem in the shoulder joint, but by a problem in another area, such as the neck, that is felt in the shoulder and upper back.
Read more about the causes of shoulder pain.
There are things you can do yourself to treat shoulder pain, including using painkillers such as ibuprofen, or ice packs to reduce inflammation and relieve pain. Avoiding activities that may aggravate your symptoms will also help.
Depending on the cause of your shoulder pain, you may need further treatment, such as:
In most cases, shoulder disorders improve over time if treatment advice is followed.
Read about how shoulder pain is treated.
You should see you doctor if your pain is the result of an injury, it's particularly bad, or there is no sign of improvement after a couple of weeks.
Shoulder pain can be a long-term problem: up to half of people still have symptoms after 18 months. A correct diagnosis will ensure you receive the right treatment.

Shoulder pain can be caused by a minor injury, bad posture, or an underlying health condition.
Conditions that can cause shoulder pain include:
Frozen shoulder, also known as adhesive capsulitis, is a painful, persistent stiffness of the shoulder joint which makes it difficult to carry out the full range of normal shoulder movements.
Frozen shoulder occurs when there is thickening, swelling and tightening of the flexible tissue that surrounds your shoulder joint. This leaves less space for your upper arm bone (humerus) in the shoulder joint, and makes movement stiff and painful.
You may find it difficult to carry out everyday tasks such as dressing, driving and sleeping comfortably. Some people are unable to move their shoulder at all.
The symptoms of frozen shoulder can vary greatly but tend to advance slowly. They are usually felt in three stages spread over a number of months or years.
Read more detailed information about the symptoms of frozen shoulder.
Most cases of frozen shoulder occur in people aged over 40. The condition is more common in women than in men.
The exact cause of frozen shoulder is not fully understood. However, there are several risk factors that make developing frozen shoulder more likely. These include:

The rotator cuff is the group of muscles and tendons that surround the shoulder joint. Tendons are the tough, rubbery cords that link muscles to bones. The rotator cuff keeps the joint in the correct position, allowing it to move in a controlled way.
Different types of rotator cuff disorder can cause different symptoms, but common features include:
The different types of rotator cuff disorders and their slightly different causes are explained below.
Rotator cuff tendonitis and bursitis are usually the result of irritation and inflammation caused by a shoulder injury or overuse of the shoulder. For example, these conditions may affect someone whose job involves a lot of overhead lifting, or an athlete who competes in throwing sports, such as the javelin or discus.
If there is any kind of injury to the shoulder joint, the tendons or bursa may become inflamed. This means there is less space within the joint for the tendons and muscles to move. If the tendons, muscles or surrounding tissue become trapped between the bones in the shoulder, any repeated movement will irritate them.
Tendonitis and bursitis often occur together. When the tendons or bursa are trapped between the bones it is often known as "impingement syndrome".
If the tendon is repeatedly scraped against the shoulder bones, it can gradually weaken and will sometimes tear.
A torn muscle or tendon will cause severe pain and possible weakness in your arm and shoulder. Some people may also feel a popping sensation when they move their shoulder.
Tendon tears are most common in people aged over 40. Tears that affect younger people are usually caused by an accident. In older people, tears are often caused by impingement syndrome.
It is estimated that around half of people over the age of 60 may have partial or complete rotator cuff tears. This is because your tendons become weaker as you get older.
The term "rotator cuff syndrome" is used to describe any type of damage to tendons in the rotator cuff, including complete tears.
The shoulder joint is a ball-and-socket joint. The top of your upper arm bone (humerus) is the ball, which fits into the socket of your shoulder blade.
Shoulder instability occurs when the ball part of the shoulder joint does not move correctly in the socket. This can range from a slipping or "catching" feeling in your shoulder to a full shoulder dislocation where the ball comes completely out of the socket.
The symptoms of shoulder instability can sometimes be vague. People with shoulder instability often describe symptoms that are similar to having a "dead arm", such as:
If the shoulder is dislocated (where the ball has come out of the socket), symptoms can include:
Shoulder instability can be either:
Traumatic shoulder instability is often the result of an accident. Atraumatic shoulder instability tends to occur as a result of repetitive arm movements, such as throwing or swimming. Shoulder instability usually occurs in people aged under 35.
The acromioclavicular joint is the joint at the top of your shoulder (not the ball-and-socket joint). Possible acromioclavicular joint disorders include:
Symptoms of acromioclavicular joint disorder include:
If the acromioclavicular joint is dislocated it may also look visibly out of position.
Acromioclavicular joint disorders are more common in men and those between the ages of 20 and 50.
People who play contact sports such as rugby have an increased risk of developing acromioclavicular joint disorders. They are also more likely to occur in people who have fallen on their shoulder – for example, during a skiing accident.
Your doctor may be able to diagnose the cause of your shoulder pain by discussing your symptoms with you and examining your shoulder. In some cases, tests may be needed.
As well as asking exactly where the pain is, your doctor will also need to know whether:
Your doctor will probably carry out a physical examination of your shoulder area. They will:
Your doctor may also ask you to do some specific arm movements – for example, placing your hands on the back of your neck and pointing your elbows out to the side. The type of movements that cause pain will help your doctor to determine the underlying cause.
Further investigations are not usually necessary. However, if you do need any imaging tests to examine your shoulder in more detail, your doctor may refer you to your local hospital. You may also need some blood tests. These are explained below.
You may have a shoulder X-ray if the inside of your shoulder joint needs to be examined to rule out other damage. An X-ray uses radiation to detect problems with your bones.
Read more about X-rays for more information about the procedure.
A magnetic resonance imaging (MRI) scan uses strong magnetic fields and radio waves to produce a detailed image of the inside of your body.
Read about magnetic resonance imaging (MRI) scans for more information about the procedure.
A sample of your blood may be tested to rule out conditions that can cause shoulder pain or similar symptoms, such as:
Read more information about blood tests.
The type of treatment offered for your shoulder pain will depend on the underlying cause and your symptoms.
Options such as heat or ice packs and painkillers may help reduce pain and treat minor injuries at home.
You should see your doctor if your pain is the result of an injury, it's particularly bad, or if there is no sign of the pain improving after a couple of weeks.
Your doctor may refer you to an orthopaedic surgeon (a specialist in conditions that affect the bones and muscles) or rheumatologist (a specialist in conditions that affect the muscles and joints) if you have:
The main treatment options for shoulder pain include:
These are described in more detail below.
As well as pain, you may also have reduced strength or movement in your shoulder. In this case, a combination of different treatments may be used.
Read more about treating frozen shoulder.
Depending on what is causing your shoulder pain, your doctor may recommend you avoid certain activities or movements that may make your symptoms worse.
For example, in the early, painful stage of frozen shoulder, you may be advised to avoid activities that involve lifting your arms above your head. However, you should continue using your shoulder for other activities, because keeping it still could make your symptoms worse.
If you have shoulder instability, you may be advised to avoid any movements that are likely to make the instability worse, such as overarm throwing.
If you have sprained your acromioclavicular joint (the joint at the top of your shoulder), you may be advised to avoid moving your arm across your body. You may also be given a sling (a supportive bandage) to wear to support your arm for up to a week after your injury.
If you injure your shoulder, for example while playing sport, you can apply an ice pack to the affected area to reduce inflammation and pain.
You should apply the ice pack for 10-30 minutes. A bag of frozen peas, or similar, will also work well. Wrap the ice pack in a towel to avoid it directly touching your skin and causing ice burn.
If your pain is mild, taking painkillers such as paracetamol or codeine may be enough to control it. Always follow the dosage instructions on the packet to ensure the medicine is suitable and that you do not take too much.
As well as easing the pain, NSAIDs can also help reduce swelling in your shoulder capsule. They are most effective when taken regularly rather than when your symptoms are most painful.
Corticosteroids are medicines that contain steroids, which are a type of hormone. Hormones are powerful chemicals that have a wide range of effects on the body, including reducing swelling and pain.
You may be prescribed corticosteroid tablets for frozen shoulder. Some evidence suggests these may provide short-term pain relief for a few weeks. However, it is not clear whether corticosteroid tablets are any better than other treatment options, such as corticosteroid injections.
Corticosteroid tablets can also cause a number of side effects.
Read more about the side effects of corticosteroids.
If your shoulder pain is severe, such as in certain cases of frozen shoulder, painkillers may not be enough to control the pain. In this case, you may have corticosteroids injected into and around your shoulder joint.
Corticosteroid injections can help relieve pain caused by frozen shoulder and increase your range of movement for several weeks at a time, particularly during the first stage of symptoms. However, the injections cannot cure your condition completely and your symptoms will gradually return.
Research also suggests that corticosteroid injections can provide pain relief for up to eight weeks for tendonitis (inflammation of a tendon). They may also improve your ability to use your shoulder, although they may not be as effective as some other treatments, such as NSAIDs.
One study found corticosteroid injections may be most effective if used within 12 weeks of tendonitis symptoms starting. However, some experts believe the use of corticosteroid injections should be delayed for as long as possible.
After having a corticosteroid injection, you may experience side effects at the site of the injection. These may include:
Having too many corticosteroid injections can damage your shoulder. Therefore, you may only be able to have this treatment up to three times in the same shoulder in one year.
Read about corticosteroids for more information about this type of medication.
Hyaluronate is another medicine that can be injected into your shoulder to treat shoulder pain. One review of a number of studies found that hyaluronate was effective at reducing pain.
If you are referred to a physiotherapist, they should explain to you what treatment they will use and how it will work. Learn more about physiotherapy.
Possible treatments include:
TENS is a type of physiotherapy where small electrical pads (electrodes) are stuck to the skin over your shoulder. The TENS machine delivers small pulses of electricity through the electrodes, which numb the nerve endings and control your pain.
As well as these treatment methods, your physiotherapist may also recommend shoulder exercises specific to your needs. For example, if you have shoulder instability, you may be given exercises that will strengthen your shoulder.
If you have shoulder pain, it is important to keep your shoulder joint mobile by doing gentle, regular exercise. Not using your shoulder can cause your muscles to waste away and may make any stiffness worse. Therefore, if possible, you should continue using your shoulder as normal.
If your shoulder is very stiff, exercise may be painful. Your doctor or physiotherapist can give you exercises to do without further damaging your shoulder.
You may be given exercises to do on your own, or you may complete the exercises with supervision from your doctor or physiotherapist. You may also have manual therapy, where the healthcare professional moves your arm for you. Manual therapy uses special techniques to move the joints and soft tissues in your shoulder.
One review of a number of studies found long-term physiotherapy was as effective as surgery for impingement syndrome (any type of damage to the tendons in the rotator cuff).
If other treatments for frozen shoulder have not worked, you may be referred for surgery. There are two possible surgical procedures explained in more detail below.
Manipulation involves having your shoulder moved while you are under general anaesthetic. During the procedure, your shoulder will be gently moved and stretched while you are asleep.
Afterwards, you will usually need to have physiotherapy to help maintain mobility in your shoulder. Manipulation may be used if you are finding the pain and disability from your shoulder difficult to cope with.
An alternative procedure to manipulation is arthroscopic capsular release. This is a type of keyhole, or non-invasive, surgery. The surgeon will carry out the procedure after making an incision that is less than 1cm (0.4in) long. A special probe opens up your contracted shoulder capsule and any bands of scar tissue are removed. This should greatly improve your symptoms.
As with manipulation, you will need physiotherapy after the surgery to help you regain a full range of movement in your shoulder joint.
Surgery may be used to treat rotator cuff tears if the tear is large or if other treatment options have not worked after three to six months. It is possible that having surgery earlier will lead to a quicker recovery, although at the moment there is not enough research into whether early surgery is beneficial or not.
During the procedure, a small amount may be shaved off the bones in your shoulder. Damaged tendons and bursae (fluid-filled sacs found over joints and between tendons and bones) may also be removed. This creates more space within the joint to allow your rotator cuff to move freely.
The operation can be performed as:
Evidence suggests that people return to work about a month earlier if they have mini-open surgery rather than open surgery.
As with frozen shoulder surgery, you will need physiotherapy after your operation to help you regain a full range of movement in your shoulder joint.
If your shoulder dislocates (the ball comes out of the socket) regularly or severely, you may need surgery to prevent it happening again and to prevent surrounding tissues and nerves from becoming damaged. Depending on the type of instability you have, surgery may involve:
Surgery for shoulder instability can either be done using keyhole or open surgery. After the operation, your shoulder will need to be immobilised (prevented from moving) using a special sling for several weeks. You will also need physiotherapy to improve your strength. Full recovery may take several months.
