My father have post covid symptoms. Fever about 99. 8f raised sometimes. So he is taking antibiotics for last one month. He has been urological issue too since last 3 years. He don't have sugar issue. But have bp issue. Last week after taking steroids his wbc increased to 21000. So currently doctor said it's an infection. This week doctor again prescribed antibiotic pheropenom compound (also earlier took). Now he has itching in eyes. What may be the reason of itching?
