Shooting pain in left breast three weeks post-op.

I had my BA (300cc, mod+, under the muscle) three weeks ago, and everything’s been pretty painless. However, around a week ago I started experiencing shooting/burning pain in my left breast, and now I also get it in the nipple. It’s in the lower part of the breast. Everything looks fine and my left breast doesn’t feel/look different from my right breast. I’m right handed. I sometimes feel it when I move my arms up high, but yesterday morning I woke up from the pain. Thanks in advance!
