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.

Thanks for that Phil.. who would normally administer the jab??

I know what you mean about the GPs... I had to have blood tests last year which the nurse would usually take - she was away that day so the GP volunteered (too eagerly I realise now...) to do it. He hold halfway through then uttered the words..."Damn, I've forgotten to.... Would you mind holding onto this for a second please?" at which point he disappeared into the next room leaving ME holding onto the letting needle in my arm! I was bruised from mid bicep to mid forearm... Needless to say I've let the nurses do it since lol..

A cortisone injection is a short appointemnt with a consultant - they can do it during a normal consultation.
My job gives me medical insurance so Sue had her first wrist done privately within about a week of seeing the gp to get the referral.
(The med insurance is one of the things that keeps me comfy in my current job ! You wouldnt believe how many consultants I've got to know around here !)
