I've used them. They are very expensive (as far as my co-pay) and I still have about 90% of them left from several years ago. I really need to discard them, but I haven't wanted to throw them in the trash for some psycho to dig out or "just in case". I wish you better luck with them, but the biofreeze is like 1000 times better for me without the insanity of the copay. If you haven't tried it already, see if a Physical therapist or a chiropractor or even a sports medicine clinic can get you some. It helps by giving the icy/hot sensation and changing the way you respond to pain. Believe me...I have tried it all and do take some potent meds, but for the topical stuff, biofreeze is the only one I can use and the only thing that helps. No imitations come close and I am very sensitive to capsacin (sp?) so it's OUT!
Good luck with the apt!!
