Hi KD and welcome! I agree with Lauri that it may be just the normal numbness as some of my arm and breast area feeling has never returned, but then I had double mastectomies. As for the swelling, it should be checked out. It may be normal or it could be the beginnings of lymphedema. If it is lympedema you should get started right away on massage. Ask your Dr if he/she knows of a qualified
lymphedena therapist. It is important to find a therapist who has been trained in the certified methods of massage for lymphedema. It is not your ordinary massage. Go to the website for the National Lymphedema Network www.lymphnet.org
and you can find out if they have any therapists listed in your area. Unfortunately, many Doctors don't seem to have a lot of knowledge about lymphedema. Or they seem to be hesitant to send us for massage therapy. A qualified massage therapist (in lymphedema) probably knows more than the Drs. Anyway, any swelling should be looked at. My Lymph. therapist says it is best to have massage even before the surgeries to better prepare the body and lymp system. Well sorry to be so long-winded. It could be fine, but please get it checked just in case.
