After only 4 treaments of laser therapy I can see changes in my left leg which I burned using a heating pad following a fall I took about 15 years ago. The skin had turned brown all around the leg except the very back, and I had a deep purple area across the middle of the brown area where I hit my leg on a bleacher when I fell. This purple area has lightened and there are several small areas at the top of the scar and on the inside of my ankles. The first treatment started some sharp pains in the left leg and I had tingling in three toes on my right foot! This is really great as I have had very limited feeling in both feet and lower legs. This problem has kept me from much sleep over the years.
