My symptoms started about six weeks ago. It seemed like the flu. Nausea, diareha, fever between 100 and 102 and stomach pain. A few days later the Nausea, diareha and fever subsided, but the stomach pain and soft stoold continued. The pain was not severe, until recently, so I did not do anything about until a two weeks later when the other symptoms returned. When I went to my PCP they sent me to the ER to be checked for apendicitis. The CAT scan came back negative. Again, the diareha and nausea and fever went away, but the pain continued. (the pain is mostly above my naval, toward to the right side of my abdomen, and now increasingly on the left side as well.). This weekend I returned to the ER again because my symptoms had worsened again. This time they did a CAT scan with contrast, but again found nothing . My PCP recenlty ordered blood work which showed that my throid ws way off. Also, I had an ultra-sound this week and it showed that my spleen is enlarged. Can my spleen be whats causing my pain? Can my increased thyroid levels be related to any of this? I have an upper GI series scheduled for next week, so I'm hoping that will shed some light as well. If anyone out there can shed some light it would be greatly appreciated.
