Are these over the counter knee brace/supports worth a poop, or are they just snake oil? I have a bad knee, which I highly suspect is a miniscus tear. Had one before in the other knee, this one not as bad. Went to the doctor, then for Xrays, now waiting to see a specialist. Went for my first ride of the year on Sun, and wasn't really bothered by it, but afterwards was stiff, swollen, and quite sore. Would one of these braces/supports help until I find out what's going on or are they just a waste of money?
