I have been have a new problem recently. about once a week I will have bad cramps and my bowel movement starts out normal and then D. I get sick to my stomach and I keep cramping but nothing left to come out. I get the chills and feel sick for hours after. To get the cramping to stop I take immodium. This happened to me Saturday and then again yesterday. I hope this doesnt mean that this will happen more often. Does this sound like IBS. Any help would be appreciated.
