In 2006 I suddenly started getting terrible pains in my left hand and wrist. Not only did it make guitar playing very difficult, my whole life was affected. I did not have health insurance. After six months of intense pain, someone suggested I google the term "Carpal Tunnel," because it sounded like that is what I had.
That's how I found Julie Donnelly's website, called The Carpal Tunnel Treatment Center. Ms. Donnelly is a therapist who developed a treatment regimen for Carpal that you can order on her website. It includes a DVD and a massage tool. Her website seemed devoid of mumbo-jumbo, and she offered a 30 day money back guarantee for her product, so I ordered her it.
Three days after starting her treatment regimen my pain was entirely gone. I stopped doing her regimen within the week and my pain has never returned.
I have no idea what disease caused my terrible six month pain. (I never went to a doctor.) I'm a musician, not a doctor and am not qualified to actually recommend health products. I'm talking here about something that worked for me.
But if you are experiencing wrist and hand pain, and your doctor does not tell you differently, you should consider visiting Ms. Donnelly's website to see if her product is for you.
