I am 8 days post op and started my breast massage yesterday. I massage with arnica cream and have been 5 times per day as instructed. I am only using enough pressure that I can tolerate. My breasts seem be more sore and slightly more swollen today. Is this normal? How hard should I massage this early post op? I am avoiding my bruises and incision so I don't agrivate it. Also, is it safe to massage with a cooling gel like bio freeze (avoiding incision site) to help with comfort and swelling?
