I had a shot of Kenalog into my knee for a torn meniscus. About 2-3 hours after the shot, I started feeling very jittery and nauseous. Had to have someone drive me home from work. Called the doctor who administered the shot and he said it had nothing to do with the injection. Within 1 hour I barely had any strength to lift my arms. Called my primary doctor and she said to come right over. She said my heart murmur which is usually very soft and can barely be heard, was quite prominent now so she did an ekg, took blood and urine. The next day she called and said my sugar level was high. I had fasting blood tests taken 2 months earlier and never had a problem with my sugar level. Four days after the injection, I got my period so heavy (I'm 53 years old and before the injection my period was almost stopping). I have never in my life had a period this heavy. Neither doctor will admit that it had anything to do with Kenalog, but I'm certain it did. If this shot gave me diabetes, I will never forgive myself for getting it done... But, funny thing, the shot actually helped my knee and I can walk without pain. I'd rather have pain in my knee than diabetes and heavy periods.
