It seems every so often, when I use the bathroom it is a painful and sickening experience. When I go my stomach cramps up, I become naushis, I get cold chills, and sweat and shake. To me I swear it is becoming a terrifying experience. What could be going on, and does anyone have any advice. Unfortunately I am like millions others and do not have health insurance so seeing a doctor would be hard to do. My diet is good as far as basically I eat chicken, fish, rice, pasta, potatoes, and every now and than junk food like popcorn. I hope someone has some information for me. Thanks.
