Hello Thank You for contacting HCM. Severe sore throat can cause these symptoms. I would suggest you following things: Take Diphenhydramine + Dextromethorphan for cough. Take levocetirizine one at night for 3 days. 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 Report to hospital if: Condition remain same after 2-3 days Any unusual symptom appears Condition deteriorates. 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
