How To Treat Raised Bump At The Site Of Incision On Face After Mole Removal?

I had 3 small moles removed on my face, close together, so 3 separate areas for stitches, I think 3 stitches in each incision. About 1 hour after the procedure, there was a raised bump in between the 2 incisions which looked like a blister. This procedure was done last summer. The doctor said it would go away, but hasn t. It s on my face so I don t like it. Looks like a small wart. Will it every disappear?
