Hello. Recently I went to a ER with a terrible back pain that tylenol wasnt helpoing. After hours of testing and lots of pain pill (via IV) of morphine I became violently ill. I told them i dont tolerate heavy pain meds but was given it anyway and like I told them I vomited violently from it. They came to a conclusion I had colitis and then admitted me and under heavy sedation I agreed because I simply wanted to sleep. The back pain I went to have treated wasnt ever really truly examined and its real cause was simply a back muscle spasm and I treated it with OTC ibuprofen. Once they admitted me they made a direction of no food or water . They continued the morphine and I continued to vomit until I refused to take the morphine anymore and I stopped vomiting. Is nofood or water a legitimate treatment for anything?
