Wrist pain? (occasionally very severe)?

No broken bones. I got x-rays. It's been happening for about 4 years...that I can remember anyway. I play flute but I don't play hours and hours and I'm holding it correctly. I do fencing but I just started last year I use to do field hockey. Sometimes cracking it makes it feel better. But it hurts in different spots. Sometimes it hurts in the bones in diff. places and other times the tendons hurt. It usually doesn't get too bad. Except one time I was writing and it began hurting so badly that I couldn't continue. That was about 6 months to a year ago. And I am not able to play volleyball. The way you're suppose to hit it hurts soo much for my wrists. And it continued hurting for a while. But then it stopped. Then later that day, at least 5 hours later, when the pain was still gone I tried pushing down clothes in the hamper and the wrist pain hurt again. A lot. But normally it's just an annoyance.
