My insurance finally approved a series of 2 ESIs and they are scheduled in a few weeks. Both are to be done a week apart. This is new for me, but I have been suffering from low back pain and shooting pain going down to my big toe for 2 years. The nurse told me they give a Versed injection IM and that's it. No IV sedation. What am I in for? Will the Versed help? Why are these done 1 week apart? It seems to me the Dr. would want a longer space to see what effect the 1st injection had. Thanks in advance.
