What Causes Sharp Pain,loss Of Motion And Weakness In The Wrist Area?

Each morning my wrist pops, loud and hard. It has loss of motion and weakness until I pop it back in place. There sharp pain that does not shoot far, only stays close to the wrist area. With more use I have throbing and aching. Minimal swelling and no numbness/pins and needles/tingling. It mostly hurts with sharp pains on the outside (by pinky but on wrist) and inside (by thumb on wrist) but the throbing is in center. Any ideas of diagnosis? History of overworking and extended periods of being pushed back (back of fingers towards elbow) from using a buffer for carpet cleaning & lots of vacuuming & carting heavy equipment. Followed by excessive use in office setting with lots of use of 10-key typing and using computer mouse. I have rested it for two months, taping carpal/wrist with sports tape and using wrist brace occasionally. The pain is only getting worse. I have had chiropractic adjustments for about 5 years on and off on this wrist. The adjustments provide relief. The problem is not being cured and going away. I have a good diet and get plenty of nutrients/vitamins/calcium/etc. thank you for your help.
