Dr Mahl of GenStem Prolotherapy Institute treated my lumbar spine and sacroiliac joints with prolotherapy. My previous doctors always treated me with cortisone injections and the effect would wear off after 3 weeks time and I’d be back in pain. The prolotherapy has seemed to quiet things down and my back now feels stronger and I’m in much less pain, able to do my activities in comfort. Having multiple sessions of prolotherapy is so much better than having back surgery and I will never have another cortisone shot. Anyone who suffers from back pain or joint pain should first be treated with prolotherapy, the natural way to healing and relief of pain and I recommend Dr Mahl. He is sincere and honest.
