Hi @holly33, You are going into surgery in excellent condition, I believe that helps. It will be tough at first. Give your body the weeks that it needs to heal. You’ll be able to some stretching after a couple of weeks, check with your surgeon.
I had a single mastectomy, flat closure, no reconstruction. At four weeks I was feeling much better, and I was back in the gym for aerobic activity at 6 weeks. I was playing pickleball at 7 weeks. I likely could have played at 6, but I was reluctant to start too soon. I’m at 10 weeks now, and have full range of motion. I have some tightness across the chest area, but I have full strength in the muscles. What type of surgery are you having?
