Hi! I'm a woman and I am having some strange lower left abdominal pain. I have been having strange symptoms and had gone to see doctors several times, also was admitted to hospital a few times but nobody seemed to know for sure about what's wrong with me. I cannot digest lactose well and often have gas in my stomach. I stopped drinking milk about a month or two ago but the pain is still there. The pain in the lower left side of my stomach increases when my bladder is about to be full, and when I lie faced down for some time. I urinate more often than normal people. I was admitted to the hospital about eight months ago and my docs thought it was urinary tract infection but it was not. They also thought it was appendix but it was not also. Last month again I went to see a doctor and he found a small amount of red blood cell in my urine. Does anyone know what could be the problem?
