I have a question...I am very concerned as for the past few days I have had a strange almost bruise type feeling in my right breast. This only happens when I go to sleep and lay on either side. I did hit this breast a few days ago as well fairly hard at work and have been doing ALOT of heavy lifting at work. Is it possible this is from all my muscles hurting or pulling something? I have no lumps that I can feel, breast look normal, soft, nipple fine ect...
