hmmm, sounds like the bone has yet to recover.
monitor it closely for another few months, and practice sparingly, maybe not an hour.
if it persists few months from now, get it looked at again. if ur really concerned, go to a specialist and get it x-rayed then.
i was really into blading 6-7 years ago, and fell backwards one time. what i did, was without a wrist guard, used my right hand wrist to cushion the impact. it didnt really hurt at that point.
i felt a significant pain in my wrist the next day. and it took almost 10 months for it to recover completely.
i didnt see a doctor as it wasnt a really significant pain, but just a dull one, but it was there nevertheless, and it affected my playing drums for awhile.
regards
