Have any of you had a nerve block for arthritis in the neck or for shoulder tendonitis? My consultant has recommended both (not to be done at the same time though ) but the neck one especially is scaring me. If you have had one or know about them are they painful afterwards ? What do you feel afterwards - do they make you feel numb like a local anaesthetic at the dentist does? Do they hurt at the time? I have an exceptionally low pain threshold.
