Cortisone Acetate and pain in the shoulder

Don't know if it is from cortizone shot but I had a shot a couple of weeks ago. Now the pain in the shoulder is mostly gone. However since then I have had daily pains in left front of my head. The worst problem I am experiencing is the constant severe sweating of my upper body. I have sweat pouring off my head, neck and arms all day long. It gets worse after eating and subsides if I sit very still and relax. As soon as I do anything or eat, it flares up again. could this be from the shot? I also have intermittent nausea and pressure on my chest.
