What Causes Swelling In Left Breast And Left Side Of Body With Pain?

Hi, may I answer your health queries right now ? Please type your query here... Hi, for about a month now my left breast and side has been swollen more so in the morning. There's a dull pain 24/7 but there's other times there's a stabbing pain that goes all the way around to my back. I also can't sleep on that side and it keeps me up most of the night. I can't take a deep breath with out the pain getting worse. So I was wondering if it should be something I should worry about or just deal with like I have been. It also has been getting worse as the time goes on
