Please see my long detailed response to craqueman on 9/28/09. I am still free of pain and have had additional Rolfing sessions since. I would only select one from the official Rolfing Institute in Colorado. This was the ONLY treatment that cured me. Do the research yourself. I am still pain free in BOTH shoulders. (7 months now) Several doctors' were not able to diagnose the cause of my pain or how to cure it. Response was surgery and cortisone shots which were unacceptable modes of treatment. I highly recommend this very little known procedure to anyone living with horrible shoulder pain. If you google rolfing, you will see several comments from folks that have been cured. No drugs, just healthy therapy putting your bones, nerves and muscle tissue back in place where they belong.
