Carpal Tunnel would be more into your hand and wrist, before I had my surgery it would radiate up into my shoulder but it was still worse in my wrist and hand, sounds like tendonitis to me.. particularly tennis elbow.. which is good for you (better than the alternative). My dad has the best results with this brace that has an air pocket, he's had his for years and years and years and that makes it super manageable.
