back pain
"Degenerated Disc in neck was replaced with a pig bone substitute about 15 years ago.  Waited too long to have surgery so I have some spinal cord nerve damage which periodically gives me a sharp pain (count of 10-11 range on a 1-10 scale) over my left eye.  Severe enough to make me stop whatever I'm doing including get off the highway if I'm driving.  Take one pill and 10-15 minutes later it's gone!  I usually take a second pill 10-12 hours later.  I some times take one if I've abused my neck more than normal also.   No side effects and it works every time!"
