Hi, for three days I have had watery bright yellow diarrea, intense stomach pain, headache, and I haven't been able to eat anything, and can barely drink liquids. The pain is intense, it feels like there's a knot in my intestines, I feel really weak. I'm drinking electrolytes as much as I can, and I have regular medication that when I take it it makes the pain worse. Should I go to the ER or try to ride it out?
