Hello Thank You for contacting HCM. Viral infection takes time to resolve itself after completing the cycle. Antibiotics do not work. I would suggest you following things: Take Diphenhydramine + Dextromethorphan for cough. Take acetaminophen for pain/fever (if occurs). Take hot water in a cup, add 1 table spoon salt in it. Perform gargles (mouth wash) with it three times a day for at least 3 days. It will give soothing effect. Take boiling water in a pot, put your head over the steam and cover whole with a sheet. Take deep breaths in it.(Avoid getting closer else it might cause burn). Do this twice a day. AVOID: Chilled water Drinks Spicy food Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. Wishing you good health.
