I am not sure what is going on, but I know something is. I'm a 25 year old female. Have had two c-sections. History of painful menstrations and passing large painful clots. I started having this sharp, stabbing pain in the upper left quaderant of my abdomen about two months ago. The pain has let up some, but not completely gone. I went to my primary and was tested for bacterial infections, all tests came back normal. When I put pressure against the area, the pain subsides. When I cough or move certain ways, the pain gets worse. I feel only what I can describe as a heart beat about four inches above my naval. I feel on the verge of passing out all the time now. I don't have an appetite like before, nothing sounds good, I eat when I must. I'm not pregnant. I feel massive amounts of pressure that come and go. I have had chronic abdominal problems, with nothing ever found by M.D.'s. I'm not a hypocondreack, what is going on? Please, please help me!!!
