I currently suffer from constipation, having about 1 bowel movement every 2-3 weeks, but sometimes when I'm not constipated, I get these severe cramps on the side of my stomach, they are so bad that they paralyze me and bring me to me knees and I basically keel over in pain, plus it hurts so bad that I usually vomit, and my heart goes into like palpitations, anyway when this episode happens my bM'S are very soft and always green when this happens, the funny things is. is that only when I get the severe cramps, I go the bathroom normaly, but I shouldn't have to go through this for a normal bm, plus I suffer from constipation, what would make this happen anyway's out of the blue, what is the cause of so much pain, any help would be appreciated, thanks, Shane
