I've used it for a while now on my knees and ankles. Seems like it works. But honestly its hard for me to tell if anything works. I even question Tylenol. All of it seems like it may work some, but its not something I feel has a very acute impact at all.
Without a controlled study, as an individual, how can I tell if my sprain got better in 6 days but would've taken 9 days otherwise???
