I was given morphine for a r. knee replacement 11-5-13 and left on it not knowing much about it. When I got to Fla. on 12-27-13, I realized I d need a refill. The pharmacist said no one was to be one morphine more than 2 weeks and prescriptions could not be faxed, mailed, or phoned across states so I quit the morphine abruptly. Bad idea and I ended up in emergency room 2 days later. I was nauseous, bad headache, stomach pain, nervousness. so they put me on Oxycotin to start a 2 week withdrawal. I suffered terribly with sleepless nights, night sweats, etc. I figured out I also had constipation from the morphine which no medical person ever addressed until I mentioned it again in the emerge. room on 1-19-14, so I m on Merilax. I no longer seem to be constipated, but I still have the severe stomach pains and overall discomfort with the feeling of passing out several hours before a BM. The stomach pain is brought on by eating or drinking almost anything. Any help? We re back in Mich. and my doctor feels my problems are still from the drug, morphine.
