I feel sick in my stomach, throwing up, can't eat, sleep, or drink. I can't take it anymore. Please help! I have had endometriosis and operated on awhile ago. I had IBS (operation) partial and then a full hysterectomy, cancer in uterus (4th stage) operation, and now crippling arthritis and deterioration of bones. The pain is in my stomach, chest, back, with no bowel movement in 5 days, no eating, no drinking in 7 day. Very weak. What is it and what do I do?
