It gives you immediate relief. But it may not treat the cause of colic. In your case it seems to be either constipation or infection or may be ureteric colic. In fact if you are constipated your condition might deteriorate after the effect of Chat Doctor.  You have not given any details of type of your pain. So go though investigations as to why this is happening to you so that you can be treated accordingly. Till then have plenty of oral fluids and fiber rich diet. You can add laxatives at night if you are constipated. </s>
