Shoot bro, I've quite trees for YEARS at a time! Allways came back eventually. If yur maybe not happy with yur gear, or ya maybe need the quick cash, sell it if you wanna.
But if those ain't the reasons, hang on to yur stuff. Do like Brian says, and stash it. Spray a little Lysol on yur saddle.
You've suffered a grievous injury and it might be a considerable amount of time before your full strength/flexibility returns. Don't let it mess with yur head too much, if ya can. When you heal up good enough to work your hand, WORK IT! Don't let it get stove up. USE IT OR LOSE IT!!! But don't go overboard, easy does it at first. Expect to feel pain. Don't stop at the first sign; conversely, don't work it too hard. But WORK IT!
Good Luck, my man!!
