I had a tumor removed from my knee area yesterday. I have 6 (I think) stitches and, at present, the skin looks very puckered and uneven. Never had any form of surgery before; will it remain looking bumpy etc or will it reduce once swelling goes down and the skin heals? Apparently wearing a pressure bandage can help the scar end up flat instead of leaving a raised bump? Also, my mum reckons that as soon as it starts to heal I can start using cream to help reduce the scarring. Anyone got any advice or tips?
