Hi i'm assuming your surgery was under your arm like mine( i had it 20 yrs ago)I had to see a massage therapist abt 6 mthsafter. She said i had scar tissue simular to a mastectomy, it was painful but once we got the blood going well and the build up of toxins massaged out it was alot better. I do alot of the massage myself because it still wants to get thick and tight. At one point I had a lymp noid to get sore and swollen but after a mamo massage did the trick. Good luck
