I use to see its ad on TV channels regularly. So, once I bought this pain reliever for myself. I had a small injury in ankle while playing volleyball. So, I bought it. It was spray so I thought that it will work very fastly. So , I applied it on my injury spot. As soon as I applied it, my eyes started to get full of tears. It was very irritating. But somehow, I managed to do it. Because I was feeling serious pain. When I applied it, the pain started to slow down. But after 15 minutes, it started to pain again. After that, I went to clinic and the doctor applied some gel type ointment and then I felt relief. After that incident, I made my decision to not to use this pain reliever again because it does not work good. It was not so worth buying it. It was totally a waste of money.
