Morton's neuroma is a condition that affects one of the nerves between the toes. The nerve becomes irritated and compressed, which results in severe pain on the ball of the foot and at the base of the toes.
Morton's neuroma usually affects the nerve between the third and fourth toes. It is rare for more than one nerve or foot to be affected.
You may initially experience a tingling sensation in the space between your third and fourth toes, which gets worse over time. This leads to cramp in your toes and a sharp shooting or burning pain on the ball of your foot or at the base of your toes.
The pain is often worse when you wear shoes that press on the affected area and when you are walking.

The pain of Morton's neuroma occurs when the nerve that connects the toe bones (metatarsal bones) becomes irritated or compressed.
The exact cause of the irritation is unknown, but it may be due to the metatarsal bones pressing against the nerve when the gap between the bones is narrow. This causes the nerve and surrounding tissue to thicken.

If you have continual tingling or persistent pain in your foot, you should make an appointment to see a podiatrist (a specialist in foot problems). Alternatively, you could visit your doctor, who may refer you to a podiatrist.
Your doctor or podiatrist may examine your foot and ask you some questions to find out:
Anyone can get Morton's neuroma, but women are most commonly affected. In particular, the condition tends to occur in:
You will probably be advised to wear shoes with a wider toe area and take painkillers to ease the pain. Steroid injections may also be given to treat the affected nerve.
If this doesn't work, surgery may be needed. Surgery involves removing the thickened tissue around the nerve (and sometimes the nerve itself) to release the pressure.

Treatment for Morton’s neuroma will depend on how long you have had the condition and how severe it is. For some people, simple non-surgical treatments are effective, but others may need to have surgery.
If Morton's neuroma is diagnosed at an early stage, treatment will aim to reduce the pressure on the affected nerve, which is usually the nerve between the third and fourth toe bones (metatarsals).
For example, your doctor or podiatrist (foot specialist) may recommend:
Resting your foot and massaging your toes may also help to relieve the pain. You can make an ice pack by freezing a small bottle of water and rolling it over the affected area.
Surgery may be needed if non-surgical treatments haven't worked or the pain in your foot is severe.
Surgery is usually carried out under local anaesthetic and is usually performed on an outpatient basis, which means you will not have to stay in hospital overnight. The operation can take up to 30 minutes.
The surgeon will make a small incision, either on the top of your foot or on the sole. They may try to increase the space around the nerve (nerve decompression) by removing some of the surrounding tissue, or they may remove the nerve completely (nerve resection). If the nerve is removed, the area between your toes may be permanently numb.
After the procedure you will need to wear a special protective shoe until the affected area has healed sufficiently for you to wear normal footwear. It can take up to four weeks to make a full recovery.
Most people (about 75%) who have surgery to treat Morton's neuroma have positive results and their painful symptoms are relieved.
As with all surgery, complications can occur and you should discuss these with your surgeon before you have the procedure.
Two possible complications that can occur following surgery for Morton's neuroma include:
If you have Morton's neuroma, you may initially feel a tingling sensation in the space between your third and fourth toes.
This is caused by irritation of the nerve between your third and fourth toe bones (metatarsal bones).
The tingling will eventually lead to pain, which can get progressively worse over time. You may also experience cramping of your toes.
The pain is usually felt as a sharp shooting or burning pain on the ball of the foot or at the base of the toes, which is often made worse when you are walking.
Some people with Morton's neuroma feel anxious about walking or even placing their foot on the ground.
The pain is likely to be more intense if you wear tight shoes, so wearing shoes that have more room in the toe area can help. Rubbing your foot may also lessen the pain.

Exactly what causes Morton's neuroma is not always known, but there are several things that seem to aggravate it. These include other foot-related problems and wearing restrictive footwear.
It is thought that Morton's neuroma may be caused by the toe bones (metatarsal bones) pressing against the nerve when the gap between the bones is narrow. This causes the nerve and surrounding tissue to thicken.
Wearing shoes that are too tight can make the pain of Morton's neuroma worse. This is because the toe bones are more likely to press on the affected nerve if your shoes are too tight.
High-heeled shoes, particularly those over 5cm (2 inches) or those that have a pointed or tight toe area, can also compress the toes and make the pain worse. This is why women tend to be affected by the condition more than men.
Some experts also believe that other foot conditions may be associated with Morton's neuroma. This is because other conditions may cause the metatarsal bones to rub against the nerve in your foot.
Foot problems that may increase your risk of developing the condition include:
Being active and playing sport can make the painful symptoms of Morton's neuroma worse.
In particular, running or sports that involve running (such as racquet sports) can place extra pressure on the nerve in your foot, which can aggravate the problem.
