I developed an indentation on my forehead. I did not bump it or caused any trauma. The only thing that occurred when I noticed the indentation was I had a cortisone shot in my shoulder that caused me to have a severe flushing reaction on my face. It lasted about two and a half days. I can t imagine this had anything to do with the indentation but it was the only out of the ordinary thing that happened. Should I see a plastic surgeon to correct this? I have no other symptoms.
