My injections into L5-L4-S1 were done incorrectly my last time and I was literally having the same symptoms as someone who overdosed on a street drug. Mainly being short, deep breathing, dizziness, racing heart rate and high blood pressure. In short, what had happen to me is the pain management doctor gave me too much ‘juice’. I certainly resent this as it was an unbearable experience. My first time to get injections it was a complete and total breeze and piece of cake by the same don’t know why I reacted on that way.
