I sure feel for you since mine went bad today. I leaned over looking into boxes too long for my treetop angel. I took a mild pain pill and it did nothing so I put on my TENs unit and it sure helps. Have you ever gone to an orthopedic surgeon? That is who prescribed mine. Actually, although it's illegal, every once in a while I see someone is trying to sell one. I (the insurance company) paid around $500 for the first one but I wore it out and got a new one a couple of years ago on the internet for $99. Medicare wouldn't pay for it though. Didn't have Medicare the first time. If you go through you're Dr., you are more likely to get insurance to pay for it. Oh, I forgot, You're in Canada. So, I have no idea how it would go there but here you do have to have a prescription here. Mine has really been a blessing. It sure beats taking pain pills.
