Hello Carrie,
AHHHHhhh feels better calling you Carrie

Thought I would do so being you "signed" your last posts as "Carrie".
Yes, Kenalog is a trade name of a corticosteroid. It is given with lidocaine to "numb" the area were the needle goes (up my tailbone lol). Only bummer is that the lidocaine affects my stability for about 45 minutes after the injection. No big deal, that way I can talk with the nurses.
The epidurals have been lasting me about 4 months. That is not to say that in between I don't have a "bad weather" day now and then which seems to be that $^%$*@ arthritis as all my joints including my ole back act up. I'll stay with the epidurals as long as they can still permit me to function in an acceptable manner.
You have provided Casey with very good thoughts, info and wisdom.
Have a GREAT Day!!!
