Hi Butterfly Child, I had an epidural procedure a few years ago. I had a ruptured L4/5 disc that was causing me incredible pain.
I think it's the same spinal block thing you're talking about. It didn't hurt very much. I had a local before they put the needle in. They put painkiller and an anti-inflammatory in there and it was so nice to be free of pain for a while. However, it didn't reduce the size of the mass enough and once the painkiller wore off I was in agony again. The drive across Melbourne after the procedure was a nightmare.
I ended up having a discectomy to remove the mass and an artificial disc inserted. The neurosurgeon said I could have the surgery and seven weeks off work, or I could wait for my body to absorb the mass, which could take 12 months or more, then deal with a very deflated shock absorber in this very vital L4/5 area. I am so glad I chose the surgery.
So, if things are not improving for you, don't be scared of the surgery. The recovery took several months but I've never looked back. I resumed an active lifestyle, which is going to get even more active in a week or so when my first baby arrives.
