I've just noticed something about my wrist.

If I passively extend the wrist (bend back of hand closer to back of forearm using other hand), then pull the wrist into radial deviation (as far as it can at that extension), then reduce the amount of extension while maintaining maximum radial deviation, I'll get to about 30 degrees of extension whereupon there's pain on the radial side of the wrist that's too much to go any further without reducing the amount of radial deviation. It really feels almost like there's a bone in the wrist in the way. However, if I start off with the wrist in full flexion and place it in radial deviation, I can go all the way to full extension, passing through the same 'region', without a problem.

Is there any danger in gently trying to increase this restricted movement - backtracking when I feel the pain? Trouble is, it really doesn't feel like it wants to go past this point in one direction.
