I am 76 old. I have unhealed incision done for removal of bunion on the ankle of right leg. It has healed about 90% but balance of 10% formed as tough skin over the incision. There are no pus or blood woos from the crest. Only problem is the crest is not falling off. But every evening pain appears every day to quench the pain I have to apply some antiseptic cream and pain disappears after about one to one half hours. The question is why it is not healing? and what should be done? Due to this I have sceitic pain on the left leg & buttocks. I am in Bangalore, India. Can you kindly suggest a doctor who can help me in curing this. I have already visited respective 3 to 5 leading specialization. They have done skin grafting twice and it has failed. What alternative therapy is available at at Bangalore.
