it sounds identical to an injury i had last year, i attempted to hit a ball that was lying under some groundcover there was some small roots and i thought my 9 iron would just slice right through them, no dice bam! my right wrist was hurting i still finished out my round but it hurt. for months i would think that it was healed and than i would take too big a divot and it would hurt again, now it is healed but i think it took about 4 months before it went away.
