I had a 10 mg. shot of Kenalog for my neck and shoulder pain.I got the shot in the left shoulder My face has been red and burning. I sweat really bad .and have a very bad headache.I would have rather suffered from my pain then go thru this. I wasn't given any information on this medication before i was given the shot.Or i wouldn't have had it with these known side affects.Does anyone know how long my face will stay red and burning i can't stand it. I will go for physical therapy from now on.
