Epidural tomorrow - Yay...? Maybe?

I was able to move my appointment from Jan. 16 up to Jan. 9th for the epidural injection to address the issue with the pinched nerve that causes pain in my left leg.  I hear these types of injection are quite painful.  I'll let you know how it goes.  I have not been able to walk normal since the 2nd week in December.  I'm getting tired of throwing my left foot out in front of me, locking the knee and then putting weight on it to take a step.
