Morton's neuroma, also called an interdigital neuroma, is a thickening of the tissue around a nerve between the toes, most often between the third and fourth toes. It results from pressure and irritation of the nerve, and it can make the ball of the foot painful.
Symptoms
- A burning pain in the ball of the foot that may spread to the toes
- Tingling or numbness in the toes
- A feeling of standing on a pebble or a bunched-up sock
- Pain that is worse in narrow or high-heeled shoes and with activity
- Relief after removing the shoe and rubbing the foot
What causes it
Squeezing or repetitive pressure on the nerve is the main trigger. Tight, narrow or high-heeled shoes, high-impact activity, and foot shapes such as flat feet, bunions and hammertoes can all contribute.
How it is diagnosed
A podiatrist examines the foot and may squeeze the forefoot to reproduce the symptoms. Ultrasound or MRI can help confirm a neuroma, and X-rays can rule out other causes such as stress fractures and arthritis. Similar symptoms can come from other problems, so a proper evaluation matters.
Non-surgical treatment
- Shoes with a wide toe box and lower heel
- Padding or orthotics to spread pressure off the nerve
- Activity changes
- Injections, selected for your situation
- Treating related issues such as hammertoes or bunions
When surgery is considered
If pain persists despite conservative care, surgery may be recommended. Options include releasing the tight tissue around the nerve (decompression) or removing the affected portion of the nerve. Removing the nerve usually leaves a permanent area of numbness between the toes, which is discussed beforehand. See also nerve pain.
Early care often means simpler treatment, so see a podiatrist if ball-of-foot pain or tingling continues.
