Cortisone injections anywhere (he says knowingly having had then in the coccyx and the shoulder at various times !) are a bit less than comfortable because there is a bit more than 'normal' going in. Therefore they are also a bit more tender afterwards - sort of like a bruise.
However, when the cortisone starts working any pain that is caused by inflamation in that area should be reduced - unless you have a bigger problem than just inflamation.
BUT !!!!! DO NOT LET YOUR GP DO IT !!!!!
It is REALLY important that the payload gets delivered on target !

Wrist Splints - are a MUST for CTS - they let the wrist rest in a position that takes the pressure off the nerve. If you wake up with pins and needles in your hands talk to a physio asap.
