You should have your wrist re-xray'd to make sure the proximal scaphoid (it gets less blood supply than the rest) isn't undergoing avascular necrosis. If not, have someone with sensitive hands to check the joint play to evaluate if the carpals are hyper or hypomobile. If they are hyper, then prolotheraphy may be in your future, if hypo, then see a chiropractor. If AVN...you're fucked.
