I've been suffering from left side abdominal pain which also goes around to my back, I've had x-ray, full bloods and ct scan which all came back negative, this has been going on for the last 4months. The pain is a stabbing pain which can leave me in tears at times I can't sleep on my left side as it hurts so much. Sometimes it eases off but is then a dull pain when it gets worse it makes me flinch/jump. I've also been constipated and am only going toilet once or twice a week and my stools are difficult to pass. I've done everything my GP and consultant have advised, I'm getting stressed and frustrated as to what is going on and do feel as if I'm now being left to my own devices, can anyone give me there good advice or opinion
