I’ve had this pain in my chest, in the center to the right of my heart.I’ve had it for roughly 3 weeks were it caused a pretty severe and sharp, it was getting worse the pain, started to go away, now returned about a week ago, and the pain is more extreme, sharp and severe than ever..It’s roughly 3 inches from dead center of my chest to the right..It doesn’t go much further than that..feeling around my chest, and I have been doing this for about a week, the pain subsided, not to subsiding completely, but the pain going from a 7-8 to 2-3, than it returned to a constant 8-9..Today I felt a bump exactly where the pain is..and pressing on it lightly Im pretty sure I found the source of the pain..Any person would have gone to the hospital, however I haven’t because I had a back infection (Fungal), that was very rare, only 39 people had this infection before, long story short I was in the hospital for 2 years, so I’m not eager to gour back, though this was back in 2003..Many sites I’ve asked pretty much reply they can’t give a diagnosis, obviously not, just asking an opinion to what I’ve stated what it could be, there are other symptoms that started when the pain started..I don’t want to write more because this is already pretty long.
