I have a bump on back of my heel that is red and has been very enlarged for several weeks. There is an open sore on it that will not heal. (I am not diabetic). I finally found a description of it at Foot.com and am wondering what the surgical treatment of it is. My doctor has treated me and I have been using wet to dry compresses on it for 3 weeks to get the sore to heal from the inside out. Also no shoes with backs for now. He has said that if it isn't better in a few more weeks, than I will need surgery. What is the surgical procedure? I am now noticing the same condition on the other heel but it is not so enlarged and currently not painful, but definitely a red bump. Any information would be helpful. Thanks. Judy D.
