In the last few weeks, I've developed pain in my wrists, especially the left one. The pain is present only when pressure is placed on the thumb-side of the open plam for instance when doing a standard push-up, bb bench press or holding the focus mits for my sparring partner. The pain is not present if I change to knuckle push ups or stiking the heavy bag. It is focused on the thumb side of the wrist.
Any ideas on what's going on and 'rehabing'?
