I have minor back pain from scoliosis and the Compex device helps relieve the sore muscles when they become inflamed. I sit in a chair in front of a computer all day long which is horrible for your back. The Active Recovery Feature has been helping get more oxygen to my muscles and makes me feel better. I am starting to see a positive change in the way I feel too from the endorphins I get from using the unit, and want to be more active from just using the unit. It makes me feel younger.
