I don't know if anyone else has had this experience, but when given morphine, it accentuates my pain rather than rid me of it. Demerol did well, but now most don't use it after surgery for some reason. I have tried sooo many pain medications but either they have really bad side effects, or they are morphine derivatives. I have fibro, ddd in my lower back and neck and because of radiation during my cancer, under my right shoulder blade is extremely painful (this is the main reason for meds right now). Have had intercostal injections twice, but cannot do another until January. meantime...
