After a total knee replacement and a broken bone in my left knee, inflammation set in. I endured much swelling, lots of pain, which even woke me up at night, my doctor sent me for PT. They started me off with heat, coconut cream, and then the Astym therapy. Yep, it really hurt, but each time it was done, the pain decreased . The inflammation decreased rapidly. I know , without a doubt , the Asytm therapy was the reason for my speedy recovery. Thank you SO much Asytm!!
