I noticed over a period of six months, my knee pain was progressing for no apparent reason. I had to stop a lot of physical activities including treadmill workouts, golf and skiing. The pain would wake me up at night, and it was even difficult to lift my leg to put on a sock. I was evaluated at Houston Spine & Sports Medicine, and agreed to a series of prolotherapy knee injections. I am now skiing again, and have returned to the driving range pain free!
