i had the same thing for a long time, i bet you sometimes throw up your food as it gets tight, its your
colon twisting up & blocking the flow therefore it gets tight & causes the problems. the only way for fixing it is to have a hemicolectomy operation, it involves a peice of colon being removed, i had it done three years ago & am glad i did it as it can become fatal, the pain is shocking i know but the surgey fixes it so seek help as its well worth it.
