Hope you're feeling a little better - I'm impressed you went to work - I went out of the house two days after my first injection (to the docs for a sick leave extension) and was about crying from sitting in the chair in the waiting room for 20mins..it took a week more before I went back to work and then it was fine (lets say tolerable) for a few days but by the weekend was worse than ever...I've been working on and off since. Next injection monday and have pre-warned work that I won't be in until the wed or thurs. Luckily they're fine with me working from home a bit for now.
Anyhow, hope you're getting some relief from the injection now. How did you get on with the first injection? It can take a few days to a week to work anyway, but then can apparently last for a few months. I was told before my first that usually if there was nothing after the secoind they won't bother with a third...not sure yet if I'm looking at oral steroids or surgery next (for foraminal stenosis).
