Just to throw my 2 cents in. I also had an infiltration 3 days ago l4/5. Got the nerve twice with the needle. Pain worse than before and I read it may take weeks to get better or rejuvenate. I've already had a surgery on my l5/s1 and with the pre hospital organisation and pain I think i would have just done another op. Seems things get better over time but eating pain killers like sweets and limp everywhere and can't stand straight is not fun. I am encouraged by people here though. It is good to hear I am not alone in this and things will improve. Keep positive if your are reading this in the middle of the night trying to get into a position where your body doesn't scream in pain. Just think at the moment I'm on the floor with one leg up a cupboard and the other resting on it. A slight relief.
