In 2014 I had a total knee replacement, it was not a success. The following year I had an Arthroscopy to clear the scar tissue, the improvement was minimal. In 2017, my knee was opened completely & the scar tissue was removed. This also was not successful. Due to pushing myself to exercise, I experienced a rupture in my Achilles Tendon, which was also painful. I have been experiencing a lot of pain at night, sitting for any period of time & unable to bend or straighten my leg satisfactorily. I was introduced to Pulse Laser Relief by a friend. I was most reluctant initially, but could not believe the improvement it has made in my life. The swelling has gone, I have no night pain, sitting in the car for long periods is no longer a problem. My flexibility has improved slightly. This small device has made my life so much easier. Thank you.
