i have been suffering from tennis elbow and took a cortisone shot today, i was told the pain mught get worse before it gets better . can i take either tramadol or percocet for the pain? i also have advil pm and a combo of paraceaml and propoxyphene in the house. i am scared i wont be able to sleep due to the pain and would like to take something. i am taking simvastatin, lotan for blood pressure , microporin 75 mg and vitamin d on a regular base- would any of these have an effect on the cortisone and the pain pills thanks
