I have coronary atery disease, have had one drug coated stent in my main atery and am on plavix and asprin. Had a shot of cortisone into my left shoulder yesterday (without lidocaine); pain was immense and was a shock to my system; Immediately afterwards, I became pale, faint, and broke out in sweat. Had to lay down on an exam table to keep from passing out. After a few minutes of lying still and being fanned by a nurse, I regained composure to leave. For the remainder of the day, my skin was pale grey, and I generally did not feel well. It was not until later that night, after two our three hours of rest, did i recover. From that point on, I had the typical restless night with limited sleep, and face began to turn red. I have never had a reaction to cortisone, and don't know if that is what occurred, but I would be curious if anyone else has had this same side affect.
