I had one of these in my shoulder at the end of July and its be brilliant up until today when my shoulder has been hurting again. Does anyone know how long these injections last for and if you can keep having them? Thanks :)
Yes, you can have them every 3-4 months, when they start to wear off. I had them in my wrist (through my carpal tunnel) and into my shoulders, like you.
I had a steroid injection into my shoulder at my gp surgery in february 2009 and have had no problems since then. He did say that I could have more if the problem returned.
I had a problem with repetitive strain injury in my arm, and needed 3 steroid injections over the course of a few weeks to get relief. That was about 18 years ago and have not (fingers crossed) had any pain since.
