I had a ct scan done on my head yesterday. I am now having a slight headache but it especially hurts when I cough or sneeze. I did not have any headaches prior to the ct scan. Are these symptoms common for people who have been given a ct scan for their brain? Or is it possible that I may have been given a radiation overdose and therefore I might have some brain damage now like bruising or bleeding due to the radiation? I also felt fatigue after the ct scan and went to bed early that day.
I would appreciate any help.
