I just had a cortisone shot in my shoulder joints at 11:30a today. I used to be able to lift arm out to side but pain. Now I can hold my arm up. I can't raise it more than a few inches and if I help with my other arm to get raised, when I try to lower I have no control. Arm just flops down. I kinda stressed out a bit. Any answers and or advice would be most appreciated.
