Had my fingers slammed in the door a few weeks ago..

[flyershoe]

I was at a wedding & we were all having a great time until we went to a continuation of the party. Had my finger slammed in the hotel room door by one of B's drunken friends. Fortunately I was fairly inebriated myself and it didn't hurt a whole lot until the next day. Middle finger got the worst of it, very swollen, black & blue, etc. Went to doc & had it x-rayed - it wasn't broken, she said to ice it twice a day & keep it in the finger splint until the swelling went down. The swelling was mostly gone last week & the splint was super annoying, so I took it off. It feels mostly okay, a little numb in the tip of the finger and it hurts if you push on the joint (the joint was the most damaged). The worst part of it right now is the range of motion -- I only have about 90 degrees right now and it still feels very weak. There's also kind of a knot of tissue on the underside of the finger, below the joint. Is there something I can do to speed up the healing and/or get my finger back to normal?

Thanks!!
