At work some times my wrists hurt on and off during work and after?

Use. Hard or repetitive use makes joints and tendons hurt. Try to cut back on hard use, increase rest time, Ibuprofen are some ways to help this. If things are really bad beyond that, then certainly have it looked at.
Repetitive use. A lot of this depends on what kind of work you are doing. Repetitive strenuous use of the hands for prolonged periods of time can cause symptoms similar to these. Conditions such as overuse syndrome, carpal tunnel syndrome and tendinitis can all be caused by this type of work.
