I have small wrists and they killed doing heavy pressing/curling and powercleans.
When the get too sore I just back off the intensity for a while. I found that high rep 20-100 per set wrist curls stretch out the flexors and pump in fresh blood to the area and work out the scar tissue.
I don't really recommend taping or strapping because they allow you to carry on having weaker wrists Just build up in volume/ intensity at a slower pace to allow the whole body to grow in line.
