Ive been on a couple of those before. I've pretty much just given up on most mess due to side effects. Also I've seen everything from general care docs to gastrointerologists to urologists to neurosurgeons and none of them can figure it out. I've had spinal taps, urodynamics, cat scans and MRIs and nothing has shown up.
The lyrica was recommended by a local doc I saw one time regarding a swollen finger. Thought it was staph so had to get a shot in the hind quarter. Luckily it wasn't.
