Mortons Neuromas
Most commonly presents between the 3/4th digits but not exclusively and causes symptoms such as a sharp stabbing, shooting pain toward the toes.
The term neuroma is a misnomer as it is more of a fibrosis of the common digital nerve as opposed to a true neuroma.
It can be caused by tight fitting footwear or increased mobility at the forefoot which can cause irritiation to the nerve.
Treatment would seek to prevent this irritation which will allow the fibrosis to settle. Conservative interventions can usually achieve this but occasionally more invasive procedures are necessary.
