I have received kenalog injections (only one) per year during allergy season for severe allergic rhinitis. I was recently out of town and was miserable and tha local ER would not give me the injection. The reason was beacause it can cause avascular necrosis especially involving the head of the femur. Which means it can slow down the blood supply to the top of the femur and cause the bone to die. I had never heard of this before and I will probably still take this injection as planned when I get back to town.
