I am having a lot of pain in my left breast -- it is an intense burning sensation. I do not have a pain down my arm, jaw pain, heaviness in my chest, light-headedness or other things I think are heart attack related. I have previously had breast cysts but none that hurt. The burning sensation is not in the middle of my chest like heartburn. I have had this sensation for 8+ hours and it has subsided somewhat but I still have the burning sensation -- as if someone was holding a match against my left breast. I took 2 Aleve about a half hour ago.
