I few months ago I had a huge carbuncle on my back and its left a huge and very ugly scar. The carbuncle was very deep and left a deep hole in my back when all the pus had drained out of it. The hole was so deep that it had to be packed by the nurse and dressed a couple of times per week. The hole has closed now but I'm left with a horrible deep purple scar. It's been this way for about 4 months. When in the shower I always blast it was hot water hoping that might help heal it but nothing seems to be working. Anyone else had similar? I thinking of getting bio oil but not sure if that's just for stretch marks x
