Pisometacarpal ligament injury

[Tyro]

Any people here who can still remember their anatomy? My wrist has been aching for two or so months because I was in a HtH combat class and two of us were sharing a boxing bag. The bag kind of moved when I hit it because the other guy was hitting it as well, and I was being sloppy on my technique at that time - my wrist was not properly locked (I know, a mistake [b(]).

I think the injury is at the pisometacarpal ligament. Can anyone confirm that this happens to boxers and what to do to 'fix' the problem? Ligament injuries do not heal quickly [*(]
