I was injected with a mixture of lidocaine and rocephin. My injection was given in my left arm nearly two years ago. I immediately went into anaphylactic shock in the doctors office. They gave me oxygen and an IV. I went home. The next day I awoke feeling terrible. I started studdering and had head and body tremors. Placed in hospital. Dismissed. Next day, same symptoms. Back in hospital. IV of potassium and magnesium. This stuff never has gotten out of my system. I have had the studdering and tremors off and on for nearly two years later, today another severe 20 minute episode of studdering and tremors. When is this ever going to go away!!!???
