Thank you, I have bad knees, but this save instantly takes my pain away. I carry it in my purse for emergencies. I also get pain in my shoulders and again instant relief from my pain. A little bit goes a long way, you don't need much, just a dab. I am going to give these as gifts. I am hitting 70 next year so a lot of my friends have a lot of aches and pain. So I want my friends to be pain free too, so I feel this is the best gift I can think of. Try it you won't be disappointed. It is so much better than taking pain killers. I hope you love it as much as I do.
