Mortons Neuroma
This affects the base of the toes, usually the 3rd and 4th. This is where fibrous tissue forms around a nerve compressing and irritating the nerve. The pain can be a sharp shooting severe pain and can come on suddenly, it can also cause numbness to the toes.
It usually only affects one foot and 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 re align the foot and to deflect the pressure, corticosteroid injection and surgery to remove the nerve.
