Sprained wrist about 6-8 months ago and it won't heal

Fell skateboarding quite a bit. It feels like I reinjured it cause I had this pain in my wrist for a long time before when I was in my teens. I'm almost 30 now and it won't go away. Steching helps but sometimes makes it worse. I wear a brace. My doctor tell me it's carpal tunnel but I don't experience any numbness. It just hurts when I bend it or put weight on it. What can I do I feel like giving up I can't pay guitar as much I have occupational therapy in a week but hearing other ppl experiences I'm worried. Why aren't I healing
