I was given some of this by a friend. Ive had frost bite on the top of my hands some years ago and anytime they are exposed to any extreme cold / wind they tend to flair up. Anyway, my friend saw my hands and said you should try this stuff. I said ok, but nothing works so Ill try it when I get home. Convinced other wise, he say no NOW ! So, I put some on the top of my hand waiting for the something of nothing magic he was claiming. To my utter disbelief my hand actually felt a heck of a lot better. So, I applied some to my top of my other hand. With the exact same results. I said I wonder if this would do anything for my neck aches? He said it should help. Off I went, still in disbelief. Next day, my neck was bothering me, and I thought oh Ill try the stuff he gave me. While it did not relive it 100% It took much of the discomfort away that I normally get. I would recommend this product to anyone seeking an alternate form of prescribed medication to temp relieve pain. I still dont get the whole how it works, all I know is trust me my hand issues is so bad when they get re-exposed it looks like someone beat the top of my hand with a hammer, then take the worst chapped skin you can think of. Its not a fun experience. This stuff actually helped it, and normally what took several weeks to heal up, only took about 5 days. I know everyone is different, I guess even typing this im still shocked the stuff works. And I guess the interesting thing is it not like your putting it on every 10 mins/ For me the most has been 5 times a day. But generally no more than 3. In some cases just one and im good to go.
