Lets say your walking home, and your brother is already walking in, hes about to close the door and you (Stupidly) put your hand in the way before it closes, and it closes on your hand

after some ice, it hurts, its nothing serious but try this so it feels better

take the other hand and lightly grip an area that isnt in pain, then put your hand on the pain area and "Roll" on it,(do a "worm" on it so at times it hurts a bit) so that it gets a bit of pressure every little time.

now, take your thumb and roll it over the pained area, its gonna hurt a bit, but its also adding pressure

basically, your "massaging" everything, so now everything is less tense, it'll work ok, but only if its minor, and if starts hurting more than earlier, stop and put ice on, and repeat

* Not gaurenteeing sucess, but it never hurts to try*

nice hint, I'll try it next time I get my hand squeezed in anything

anyways, do not lightly believe that nothing serious happened ... when I was at university a couple of months ago, a person I occasionally sat together with joined the group with a bandaged hand. What happened? I'll quote her...:
