I've had excessive liquid diarrhea for three days now, and it has only gotten worse. Now I'm experiencing severe bloating, and whenever I go to use the restroom, I only get a horrible cramp in my lower right abdomen area. The upper part of my back to the next is in constant pain, so in my middle back. Every time I try to sleep tonight, I just feel like I have to go to the restroom, where I just start cramping. What should I do?
