maybe you could try some cissus quadrangulus...
or you could make your wrists stronger with some grip work.
ive got a pin in my wrist from a bone graft that didnt work-
it used to ache alot and i`d wear a magnetic wrist band which worked well-
i dont wear it much these days and i`m sure thats down to my grip strength
einsteins mind was the key to all things...to understand more than to know.
