It's working for me.
I don't know if it's all in my head, but then again pain itself is all in our heads since that's where our pain signals are interpreted - so what difference does it make as long as it works?  I have a neurological disorder that causes neurons to misfire and create pain where there is no injury, along with pinched nerves in my spine which are real.  For me, this little patch actually works - creating a noticeable decrease in the pain.<br /><br />My guess was that the varying reviews mean that it works on certain types of pain for certain people, so I decided to give it a shot.  (I also chose to completely ignore any scathing review that said "I haven't tried it but I'm certain it doesn't work.)  I'm glad I did - I'm very happy with this purchase.  My only complaint is that I wish there was a more flexible version that I could use on my neck. One of my pinched nerves is at the base of my cervical spine, and I can't get the patch to stick that high up.  Other than that - well, I just ordered the refill package of adhesives.
