So my CT scan results are back and it seems in my L4/5 area I have a reduced opening to pass the bundle of nerves that normally route through there. This is pinching them and causing some trouble obviously. This is the same area I had trouble with 5 years ago (Spondylolesthesis) and there is now evidence of arthritis starting there. While I have some specialists to talk to first, my doctor is recommending a steroid injection to the area and believes this will provide me with much relief. Anybody had this done recently? How did it work out for you? What is a steroid anyway and what will it do to/for me? How big is the frickin needle that they use to do this??
