Horror of horrors, I wore the bra post mastectomy (with a pad) as I did before mastectomy. With a wire! It didn't impact directly on my scar, which healed very fast and felt perfectly comfortable. I only changed when I (finally) could move to a prosthesis. There's lots of different advice, all well intended, but in the final analysis, hurting is a pretty good sign it's not working well. Ditching the bra that hurts is unlikely to do any harm, keeping hurting is miserable and dents your confidence. Chat about it when you next see your surgeon. Six years after, I still have some loss of feeling in my underarm, that's not unusual. Best wishes.
