In light of the coronavirus (Covid-19), what should I do if I have a sore throat for more than a week?

Thank you for your question. I would need to understand your symptom better as the throat is a symmetrical structure and moves symmetrically (right and left sides) on swallowing. Since you mentioned that you have a "flu" a few weeks back and it appears to be coming back, there is a possibility that you may be feeling the mucous from the back of your nose flowing down the back of your throat (maybe more on the right side), hence giving you the feeling that your throat is "moving to the right".

Thank you from your question. From the clinical history provided, it sounds like you may be suffering from Rhinitis (Sensitive nose). Rhinitis refers to inflammation of the nasal cavity and can be allergic (due to exposure of a known protein, most commonly house dust mites), or non allergic (due to unknown causes but may be triggered by change of weather, perfume smell etc). Common symptoms of Rhinitis include blocked nose, clear runny nose, itchy nose and eyes, watery eyes and a postnasal drip.
