This is where fibrous tissue forms around a nerve, compressing and irritating the nerve. The pain can be a sharp, shooting pain, and can come on suddenly. It can also cause numbness to the toes.
It usually only affects one foot and it is rare for more than one nerve to be affected. This can develop from irritation and stress to the nerve in your foot over a long period of time. Repeated irritation to the ball of your feet, such as running, can lead to a neuroma developing, or by wearing shoes that are too tight.
Treatment includes: foot mobilisation to release the nerve, orthoses to realign the foot and to deflect the pressure, corticosteroid injection, or surgery to remove the nerve.
