I am recovering from a mastectomy on my left breast that was performed on Sept 1, 2022. I had 2 drains with 2 collection bottles. After 1 week, 1 drain was removed. A week after that the 2nd drain was removed. I have swelling under my arm pit still 2.5 wks post surgery. Surgeon told me it takes about 1 month for the swelling to go down. I hope she is right. Didn't you have drains post surgery? Also, I am to start chemo..meet w oncologist this week, and not sure if I should wait til swelling goes down for me to start chemo.
