( This was somewhere around 10 different drugs for chronic pain that I have tried, but with the exception of Tylenol #3 & cyclobenzaprine, there is nothing that helped enough to endure the side effects, which included severe mood swings, difficulty urinating, disorientation & hives! (What is this stuff, anyway?)
At any rate, I am again experiencing these flashing-pain headaches, & nothing seems to help.
