Hi my friend -- most likely it will be a steroid injection. Sometimes these work, and sometimes these don't. I've had MANY of these and not ONE of them worked.

The reason I had so many is because I went to 3 different pain clinics and even tho I told them that the steroid injections didn't work, they INSISTED that I have them anyway!

Didn't make sense to me, but oh well.
I've talked to hundreds of people thru the years, and percentage wise, most people had no luck with them. The ones that did, got relief for a very short time. These injections are just "band-aid" procedures. They sure aren't cures.
I hope you get SOME relief somehow. Unless your spinal cord is compromised or you are at risk for permanent nerve damage I would stay away from surgery completely! I'd try every single conservative method at my disposal. Surgery begets more surgery and often leaves you in worse shape than before (that's me). So best of luck and I pray you find some pain relief. God bles and please take care. Hugs, Lee
