Consider the shingles shot? There is no consider. There is only getting. Its painful as hell. I had considerable muscle weakness in my left leg. I was unable to lift it to get into my car. I had to pick it up! Took 10 sessions of PT and working out on my own to get my strength back. I now know what to wish on my worst enemy. I still have a lack of feeling on the inside of my left knee (when I touch the skin).
