My surgeon called them lots of things Lipomas Grauloma suture scar tissue I have had 4 big ones removed and still very many Im 6 months post we have massaged aggressively for 6 months. It wasnt until I had sent many emails before he started to reply and my revision he said would be painful I was awake for lumps removed and awake for flank revision numbed it but he went out of the areas he marked. I was numbed well when he removed the bigger lumps. I dont go back for another month for more shots
