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..Any questions please feel free to contact me..Sincerely, P.
