ah yes the old arms over the head- i don't know why it isi soooo comfy that way, but i do it too.

I have in the past used pil-o-splints which are supposedly for carpal tunnel, but good for tossers too. but they are comfy to sleep in and keep your hands opened up. with them on i am not as likely to bend my wrists, and arms over the head is not as comfortable. when my wrists hurt a lot they offer some great pain relief.

i don't know if amazon's price is any good, they are available all over. I bought mine in the local drug store, so i was able to try it on before shelling out the $$.

totally machine washable and you just slip your hand in and out, takes but a split second to put on and off.
