I went in for a "saved by the scan " ct because I had been a former smoker and I had to have the procedure redone 3 months later because I had "ground glass" in my lungs which prevented clear images in some areas. They said this is often from a disease like covid-19, and when tested i found out I had covid--so after 3 months it was redone, covid had cleared up and the images were good. Prayers for you and hoes for quick resolution.
