Bio Freeze is awesome, I definately swear by it.
Between my boxing career and baseball I had torn my left rot. cuff about 3 serious times and a dozen minor times and Biofreeze kept me going.
Just simple warning (and I'm sure your not as stupid as me)
If you put it on your feet (swollen, sprains, whatever)
Dont immediately put your shoes on then work out.......good hell it was like the fires of hell in my socks
And obviously dont whipe your eyes or scratch your sack.
Ha Ha sorry man but yeah I love the stuff and swear by it.
