These are such helpful comments. Thank you! I went to see my radiologist and she said I have some lymphedema, so I start PT on Monday. She said massage really helps to break up the scar tissue, so I hope that works for me. I don't have the underarm issue--under the breast mainly. Going braless for more than 24 hours seemed to help, and my yoga class yesterday felt great. I wore a sports bra for that and I feel some discomfort today. I did buy bigger bras--increasing from b to c. I probably should have done that from the beginning. I can't tell if my breasts are permanently bigger or just swollen.
