medical hand problems?

[willie55]

i work behind a computer and notices that mostly everyone has had carbotunnel syndrome over the last 15 years, i have never had any ergonomic related problem, which i believe is because being a conga player, percussionist we keep our hands and arms fit. and are able to do repetitive movement. the only problem i get is sometimes my hand will want to slightly close. my question is has anybody gotten a work related repetitive movement injury, while being an active percussionist?
