Will a steriod epidural shot raise bg's like a cortizone shot?

Yes. At least it did for me when i had one several years ago.

Was it worth it to you to get it? Would you do it again if needed?

I have seen several people who said yes it does. For me it lowers mine for about week and half to two weeks. I get them every 12 weeks. They aren’t perfect but I will keep up with them even if they raised my bloodsugar.
