CT SCAN type to get post covid. Covid.

Hi Doctor, I recovered from covid 2 weeks back and had cough and cold till 1 week back and I have taken pulmoclear as per doctor when I got yellow mucus and some feeling in lungs that I have mucus now after taking medicine for 5 days I feel the cough is reduced and cold got relief but still there only on right nostril from beginning. Now today morning while sneezing and coughing I get dark red color mucus and am having right eye pain from 10 days in middle 2 days it went down but now it's there very minor pain, pain will keep reducing from morning to evening sometimes on eye. So planning to take CT scan so what is the test name to ask for post covid to check for this mucus and does CT scan will help to identify "black fungus" Which observed post covid.
