How long should a cortisone shot last?

Question

My husband got one in his spine for back pain

Answer 1

If the shot worked...it should last 2-3 months.

I've had 3 of them in my lumbar spine and none of them relieved my pain for even a day.

Answer 2

I'm not very optimistic of these shots. I had 3 of them in my lumbar spine as well, and they didn't do anything. But it was another step in the ladder on the way to surgery. To me, they were a waste of time. Hopefully they will work for him. Good luck
