A neuroma is an enlarged, inflamed nerve in the ball of the foot often between the third and fourth toes. It is immensely painful although the initial pain can often be relieved with conservative measures such as ice, rest and keeping the foot elevated.
Unless treated professionally, the nerve is likely to continue to become more inflamed and painful. These neuromas can be confirmed on ultrasound scanning and if they fail to respond to injection, they can be removed with an operation.
Delicate surgical techniques involve removing the thickened tissue around the nerve, and sometimes the nerve itself, to release the pressure.
