I have had two in my L4-L5 region. The first one helped for about 3-4 months and went off w/o a hitch. The second one hurt when they did it and didn't help at all.
I went for quite a few yrs w/managing my disc pain by myself. As soon as I'd get leg pain/back pain, I'd lay low and let it simmer down.
Well, now I'm suffering from intense back/leg pain again and found out that I have L4-L5 disc that are bone on bone and a large bone spur has developed. Getting an MRI next wk, but they are talking epidurals again..
After the 2nd epidural, I swore I'd never have another one, but right now, I'd do just about anything..... take care all.
