I have breast/chest pain all the time. I have to exercise my arm on the side that the cancer was found and the nodes were removed every night while rubbing the arm pit. Small price to pay for being cancer free (at least I hope I am).
Always check with your doctor though. Women have very different symptoms than men when they are experiencing a heart attack. So always check with your doctor. If we have learned anything on this journey we have learned better safe than sorry.
Hope you are doing well and continue to do well for a very long time my friend!
