Harley had surgery last Thursday to debulk an infiltrative lipoma on his front limb.  He had this surgery twice before and walked out fine the next day with no limping.  Well, this time he came out limping worse than when he went in.  The surgeon also put a drain in which he did not need the previous times.  I took him in yesterday to have the drain removed but she left it in yet and re-bandaged the leg.  She said a seroma had formed.  She feels the limping is due to soreness because the tumor was twisted around his muscles really badly.  I'm worried about the limping.  He is scheduled to go back next Monday and hopefully have drain, staples, bandage removed.
