Hi roz
I had my breast removed last October. I have pains in my arm on and off. It appears to have increased now the winter has started. I go swimming a couple of times a week.(swim 2/3 miles a week). I know that they say repetative excerse is not good for the arm but i have found that it has worked for me. It has not stopped the pain but eased it off. I have been told that it is just something you have to live with.
