I tested positive for covid 19 5 weeks ago and negative test about 3 weeks ago however I am still experiencing post covid symptoms of nasal congestion, runny nose ,sore throat and tiredness. I have been prescribed amoxycillin antibiotics for a suspected bacterial infection however after 1.5 courses of this no improvement in symptoms. Please could someone advise me of what to do next and what treatments could be available for the post nasal drip which seems to be causing all these issues thank you
