Hi, in the last two weeks i have had four spinal cortizone injections .. in the last week my lower shin at top of inside of ankle swelled up, was very sore so i could not put weight on it and it was redcraw and hot to touch. It has left me with acred mark. Then on my wrist another one came up same symptoms and has left me with big black bruise looking mark which is sore also. Could this be acreaction from the cortizone or something to worry about. Thanks
