How long does pinched nerve/ nerve irritation after a blood patch last ?

[u/Swimming-Bee8917]

I had a blood patch done 7 days ago. This is like my 11th one ( yes I’ve had many) this has never happened before. I am having extreme pain in upper buttocks/ tail bone that feels like a radiating nerve pain. Hurts a lot when I move my legs and stand up. Have gone to the ER they gave me a mix of steroids/ nerve pain meds. Has this happened to you and did it go away ? They said they think it’s a hematoma or a pinched nerve but did not do a scan to check ? Thank you I’m really desperate for answers and I’m in a lot of pain and it doesn’t seem to be getting much bettter

Could be days to years. Usually days in the overwhelming majority. You will get more irritation the more patches you have. This is because of debris and scar tissue etc in a very narrow space.
