I have had nck and now back stenois. I had surgery 4 years ago as I couln't get my arm around my head. I hve been on a pain pump for several years as the pain became extreme. Now I have pain when I swallow and can't eat much at one sitting. The pain is much worse and I am wondering if I have a withdrawals with my pump. The Dr, added buvicaine to my morphine pump and it cause problems with bladder and bowels and i have become short of breath the past month. Can anyone ever been on the mixture of morphine and buvicaine? The Dr, lengthened from 2 mo. to 4 mos for refill. I am getting so sittery and blood pressure is very high. Any suggestiongs? I just ate something light and it caused irritation in my neck going to my esophogus. Thanks for any help, Marlene D.
