I don’t recall; for myself the epidural (ESR) was not effective for me. The PRP and mesenchymal cell injections showed improvement after a few weeks and lasted 6 months in my case.

@kensie123 Epidural spine injections may take a couple days for their full effect. That was also my experience. For some people they help for awhile, and others no so much. My injection took away all my pain for 2 weeks, then it started to return slowly and the effect of the steroid wore off by a month or 2. It takes about 6 weeks for the body to metabolize and destroy the injected steroid.
