MORTON'S NEUROMA
A Morton's neuroma is one cause which is pain beneath the 'ball' of the foot. It is due to an inflammation of a nerve in the foot. This is caused by entrapment of the nerve under the metatarsal head.
Symptoms usually begin with pain and numbness in a specific spot in the 'ball' of the foot. It may feel like a small stone or marble under the foot.
Diagnosis can be difficult at first and several examinations may be necessary.
Treatment can be conservative (no operation) or surgical.
Surgical options have a 90% success rate.
