Help with finding the correct specialty?

I know this is not for hand specialty- however, since I have not found ANY results for my hand condition I thought it might be a condition that effect the feet as well. My metacarpals on my left hand specifically my pointer finger, comes out of place and rubs against my middle finger. This happens when I am grabbed by the wrist or when I set my hand in a wrong position. No swelling occurs- just severe pain. This has been happening for at least 15 years now- and it has only gotten worse in the past few months. It used to pop into place quickly with hardly any pain, now it shoots to an 8-9 on the scale and doesn't go in for several minutes. If anyone can direct me to a different forum/ website/ diagnosis that would be fantastic. Email ***@****. Thanks!

sounds like it is dislocating.  i would go see a hand surgeon and get this fixed b/f you destroy the joint and develop arthrosis
