I injured my hand yesterday playing with my son. I think I over extended one of my fingers and injured a tendon. One might argue that this is not a "sport" injury but I though a sport medicine Dr. might be the best place to start. does any one know a good Dr. for this kind of thing?
The best sports medicine guys I know of are Nathan Breazeale and Doug Elenz with Austin Sports Medicine. This may be more of an issue for a hand specialist. Good luck!
You could also try a chiropractor who does extremity work. Mine does - Dr. Jeffrey Brown, American Chiropractic Clinic @ Steck and Mopac.
