Cortisone Acetate and aching

Had a cortisone shot in my foot(sesamoids) and I came home with a BIG puffy, swollen aching foot in the sesamoid area and toes. Had that for at least a week. And also a red colored circle (not just a ring but an entire circle) around where the injection took place on the top of my foot. Someone told me it looked like it had burned my skin. After 3 weeks it is still there but the circle is peeling a little. Was flushed and tired. Felt "not right."

Also, the dr. told me not to hyperextend or my bones may break...Greeaaat...

I am considering just dealing with the pain. The pain of the shot was enough to make me not want to do it again (that plus the stupid circle).

Anyone have a circle? I am dying to know what it is.
