It it is hard it may be a tumour (an abnormal growth). If it is a soft it could be a cyst (a bag filled with liquid). Either a tumour or a cyst has to be removed. Cysts can also be treated by an injection, which is called sclerotherapy. Please visit a dermatologist (dermatosurgeon) or an orthopaedic surgeon to get the condition diagnosed and operated. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore.
