Wrist range of motion during circles

[Deadlocked007]

Recently I have noticed a slight decrease in how far my right wrists bends back without forcing it down and a lot of grinding and cracking if i rotate it, especially when my right hand is in a fist. It has become very frustrating because it has become hard to hold a handstand in place  and while doing circles(i go counterclockwise) as i go over the left side of the horse i cannot lean far enough anymore and they just fall apart. Does anybody know what is wrong with my wrist or how i can fix this? Ive been stretching it and strengthening it in all different ways. I even tried taking a break but nothing works. Sorry if my explanation isnt detailed enough its hard to explain i guess.
