I have never been a high note player and the best I can be assured of is one note higher than I am expected to play at the time. But.. After visiting my physician for a bad case of poison ivy, he gave me a steroid shot to help cure it. In the past two weeks I have been stuck on F# above High C but this morning I went right up to a double “C”. Coincident or not, that is the question. Has anyone else had the same results after a steroid shot?
