Works well [SEP] I bought this to use on the tendon at the ankle.  It has work great there and I only have a few twinges once in a while.  I will continue using it till the twinges top.  I have tried using it on my knee, but at times it does not see to be working.<br />I do love the scent of it.  It is not heavy and it does not smell like menthol.
