I am 43 and I had the same procedure as you, but mine was stage 1 with clear nodes and margines in only one surgery. Stage 0 is highly curable though, so dont worry too much, anyway, I didn't developed cording until 4 weeks after the surgery and Lymphedema 3 months after radiation. My surgery recovery wasn't bad I fell fine almost the entired time after surgery, but I was able to do weights at the gym after 6 weeks. The lymphedema is a real thing after radiation. It's not as bad for me, but it goes and comes back on and off. I go to the OT (occupational Therapy) to get my lymph nodes drainage manually. I am on Lupron and Letrozole and the medication side effects has done to me more than the surgery or radiation ever did. Good luck and keep us updated.
