Ya, I got the band for my left arm. It helps.You use the bands for tennis elbow? They’re awesome. (Coupled with 2 Tylenol and 4 ibuprofen)
I'm also trying to wear wrist support / stiffeners since I learned that the "elbow" stuff isn't really from the elbow, but due to using the wrist too much / wrong.
I had SUPER bad tennis elbow in my right arm 3 years ago (from using a hammer to break up concrete... totally killed my arm 2 days later), and it lasted for over a year!!! It was so bad I couldn't even play badminton with my daughters. Insane!
