Hello, I have been having stomach problems for about 2 years, I get extremely bad acid reflux and bloating and wind, but for the past few months I have had very painful stomach pains and I had a lump kind of thing in my lower bladder that lead to the top of the penis which has since gone (the doctor thought it might have been a hernia) the colour of my stool is very odd indeed. Sometimes it can be very clay cloloured and pale with white chunks and just this morning it was rather dark maybe greenish with lots and lots of black specs in it. (I hav had blood tests and i dont think anything is wrong with my liver and am awaiting a colonoscopy) Could you please tell me what this might be as the stomach pains are extremely debilitating. Many Thanks
