neuralgia
"I have been taking lioresal (baclofen) 10mg 3 x per day, for 3 days now. The side effects are immense! After 20 mins I lose all sense of balance, get a major headache, and need to urinate frequently (which is difficult when lack of balance screws up walking ability!) It knocks me out for hours. Side effects last approx 6 hrs. I have cut down to twice a day now because I can't handle the side effects. Only positive is the pain eases (I have intercostal neuralgia) but not 100% pain relief- maybe 70%. I plan to visit the Dr and get off it asap."
