Cutting of my arm to spite my doctor

On December 19, I had the long awaited cervical epidural injection.  I have to say, it wasn't nearly as bad as I thought it would be.  In fact, having the IV put in was probably the worst part of the procedure.  I didn't feel too bad at all that day.  When I arrived at the doctor's office, I had virtually no pain at all - I had been feeling pretty darn good for about 4 days prior - and had really gotten my hopes up that I was healing.  Reality check:  at about 6PM the night of the CESI, I seriously was contemplating going to the ER for some morphine - that, or amputating my leg with my husband's circular saw.  I had the most intense burning in my left leg and hip, and my right hip and knee.  I mean, it was off the charts!  They told me to keep a "pain diary" after the shot and rate my pain on a 1 - 10 scale.  Literally every day it has been a 10+.  Originally, my orthopedist told me he thought this CESI would also take care of my shoulder pain because he felt it was referred from my neck.  Let me tell you, before I had the CESI at least I knew where I hurt and had a general idea of where the pain was coming from.  Now, who the hell knows?  My whole neck, left shoulder and left arm are on fire - feels like an orangutan has been swinging from my left arm for about a year and it might fall off any moment.  I don't know if it's my shoulder that hurts, or my neck or both.  And they NEVER stop burning!  Seriously, I feel like I am truly losing my mind.  I would rather submit to water torture.  I would like to cut off my own arm and beat my doctor with it - repeatedly.
