I've been using Tiger Balm ever since I was little. My grandmother's remedy for everything and anything lol. I will say that the Extra Strength has done wonders for me, especially days after work outs. Definitely would use this before any other brand because it works. Weird that I actually like the smell of Tiger Balm. I have used it on my shoulders, back, ham strings, and calves. If you haven't tried Tiger Balm, I suggest you do.
