I’ve had three lots of facet joint injections and two lots of caudal epidurals. The first round of both worked for me. Pain was reduced massively and recovery was only a few days. The second and third rounds did nothing. My “discs” were herniated too far for the injections to mask the pain.
The injections will only treat the symptoms, they won’t cure the underlying problems. But what they can do is allow you to gain some pain reduced movement, and combined with yoga, Pilates, and other exercises and physio, get you back to some sort of normal.
Injections are normally the second steps in treating chronic back pain, if rest, physio and time doesn’t work. Has the Mrs had an MRI yet?
In my case surgery was the last resort and was needed. I’m glad I went that route. It was not pleasant at the time but in the long run was the best decision.
