peripheral neuropathy
"Extreme peripheral neuropathy in both legs from knee down. Without drug I have extreme burning sensation and muscle cramps in those areas. I had been on 60 mg. Methadone for about 20 years for joint and muscle pain. When I first took Gabapentin I got side effects of extreme nausea, headaches, and general around  not feeling well so I stopped taking the Gabapentin. A new doctor insisted I stopped taking the Methadone pending an electric neural stimulator insertions to my spine. I detoxed from the Methadone at 5 mg. a week and after twelve weeks I was off it.  When I started taking the Gabapentin it worked superbly, problems reduced about 90-95%. Shift to 40-50 mg. Percocet per day took care of joint/muscle pain about as well as Methadone."
