Hello, I have been suffering with stomach pain for years. It stared when I was age 12 and has continued on, I am now 22. I can go weeks ( 1-2 maybe 3 weeks) without a bowel movement. After so long I get a pain in my left side that sometimes causes a pain in my back. On a really bad occasion I set in my bathroom unable to use the toilet, my limbs get tingly and I turn very pale and feel like I am going to pass out or die. I strain until I go and once I do I feel much better. Although it can take a day or two to get back to myself. When I do move my bowels it can vary from being a hard stool to being like a curdy water texture. I have had many tests done but nothing has ever showed up. I feel as though my body goes into toxic shock or something I have brake outs on my face and my lips feel as though I were having a allergic reaction. I have gone to so many doctors and have visited the ER to many times to count and have not gotten any help. I feel scared that there is nothing anyone can do to help! The days between getting sick I feel miserable just tired all the time and not feeling well. I am wondering if there could be a underlying medical condition that could be causing this and if so is there anything I can do?

Note: I have tried eating a healthy diet high in fibre , drinking plenty of water and have tried to live an active life style.
