Dr. Judith Mairs-Levy answered this Side Effects Of Cortisone Injections The closest thing I could possibly relate it to is ROID RAGE???.
My child was literally having baby 'roid rage, and I mean that with all seriousness. The medication side effects were ten times worse than the actual ailment! . Prednisone can give people crazy reactions at all ages, I know.
