I was given prednisone,,It was orally prescribed,,,It was in a pack that you took 6 4mg tabs the 1st day then 5 the next and you staggered down for a week,,The loading phase made me mentally agitated,which the instructions said would happened,,after day 3 on the tappering off, mentally i was better but it took ALL the joint pain away,,,the downside to this is,,I just had a Total hip replacement done a few months earlier,and predisone causes degeneration in bone exspecially in the hip joint[see in structions].so my ortho Dr didnt want me on them ,he want the healing processes not to be hindered...it was my pain mangement DR that prescribed them..either way,,they worked on pain relief for me,Although I know your daughter is probually doing the shot,,but in a way,,same concept,,,,as posted above,,it is a powerfull anti-inflammatory,,and works well,,but sometimes[as everything else] with a price,,,,If i could do the injections,,i would,,but I dont have any insurance
