From Amazon: "I am a natural born skeptic...and I never seem to have the time to write reviews. Nevertheless, I felt duty-bound to not only other tennis elbow sufferers but to the inventors of penetrex as well...so I MADE the time. I've been using this stuff for about 2 weeks and as I write this there's just one thought in my head. Why didn't I get started with Penetrex 6 months ago?!? My tennis elbow pain has almost disappeared and Penetrex did the job that various other things I tried could not. And it did it at a fraction of the price. I am only too familiar with the physical AND emotional devastation tennis elbow inflicts on its sufferers and if you're reading this and going through the nightmare, you have to order this stuff!!"

So... works for tennis elbow. Anyone use it for shin splints?
