The same thing happened to me. I was five weeks out of a bilateral mastectomy. I saw that my right side was red on Thursday. I was in the operating room on Monday getting the expanders out. I went home with a wound vac. The drains and wound vac were only in a week . My doctor wanted me to be on recovery for 6 weeks after that. I took it slow. I still walked and was mentally getting myself ready to go back to work.
