I have been suffering with acute tendinitis in my left foot or over 2 years. I’ve worn the boot, had an air cast, cortisone shots and countless shoe orthotics and topical pain creams. I have gotten more relief from PainPatrol than all these treatments combined. I use it before and after every shift and have noticed significant relief. It seems to keep the swelling down and it certainly reduces the pain. Thank you PainPatrol.
