I had covid and doc suggest HT CT SCAN, within period of week I developed sinusitis, my nose pain did not reduce even after 3 weeks and completing course of antibiotics suggested by ENT , later did plain CT scan of head nose and sinuses , results were normal , is it dangerous to have 2 CT scan in a gap of 3 weeks ? I get irritated looking through internet , I feel I have health anxiety.. still I need to get clear things of my mind
