hi, i have a sever backache that started 6 days ago with fever, dizziness and a stiff neck. on the 4th day i fainted and i was brought to the hospital, they ran all different types of tests; blood test, urine test, x-ray, and an ultra-sound but they weren t able to determine anything since they results came out all normal. They gave me 2 doses of morphine for the pain, i was going to the washroom more often than normal. the second day they discharged me and told me that they assume i had a kidney stone that fell without them being able to track it. I went back home and slept and when the effects of morphine was gone i got the pain again and was brought to another hospital, fainted at the entrance, they gave me morphine, did a scan for my back and they weren t able to determine the cause, they discharged me and gave me a pain killer. they assumed that it was a muscle pain. i am home now feeling all weak, have a stiff neck and the backache is still there but not as strong. what do you suggest i should do?
There are non morphine pain relievers also having same pain relieving effects, for e.g.  Tramadol. You may consult your doctor for substitute in tablet form
