I have pain on lft side.if i eat.have taken senocot in case of constipation . but had bad diarrhea last tues.& very very little food since then?

Avoid laxitives: The pain could be caused by the senecot, which i would avoid. Make sure you are taking in plenty of fiber. You might try a stool softener, like colace (docusate sodium) or surfak and avoid stimulating laxatives. For diarrhea, try drinking some gatoraid. For occasional contipation, try a teaspoon of epsom salts in a glass of water. Avoid laxitives.
