In reply to Removed UserSamAllen:
Sorry to hear that (climbing in font in august? You're crazy!!) anyway i think that could be an interossei palmar muscle that was partially tore...it's pretty common usually mistaken with a finger pulley since in most cases there is an audible pop sound. The pain should be localized in the base of you finger and especially on openhand grip (am i right?). Don't worry, if that's it i'm sure it will go away with a bit of rest and gentle loading...don't know the severity of your problem but you should be able to climb for august! Good luck
