What percentage of people get worse pain that does not subside into better pain after epidural steroid injection?

This is dependent on: The diagnosis for which the injection is being given and on the technique used, i.e., image guided. In general, 50% experience good relief and the rest do not with a 1-2% rate of a spinal headache and equivalent percent or less feeling temporarily worse for a day or two.

Pain: A lot. There is an assumption that back pain always comes from the spine. This is too simplistic. If ur pain did not get better...Look for other causes.

Rare: Usually less than 5% have that happen.
