Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I had a mole removed from the bottom of my back over 20 years ago. It was benign. The scar has always been sensitive but never really bothered me. Recently a painful blister formed over the scar. What could have caused it and what can I do to ease it?
