Will a Lidocaine patch help with the pain associated with Osteoarthritis?

Yes. although lidocaine patches are pricey and a little dangerous, and the pain relief is short lived. This is a transderm patch, so most people -- doctors too - don't think about how the lidocaine is delivered. The closer to the heart, the greater the chance of cardio-effects. The back, knees, elbows -- all great. but do keep in mind it does a significant lidocaine load, which can slow the heart. If you use lidocaine patches, make certain to read the precautions on the box. One last thought -- if you have kids or pets around, be CAREFUL how you disposed of the used patches. They're dangerous to leave lying around.
