Thanks for your question on HCM.
I can understand your situation and problem.
By your history and description, possibility of upper
respiratory tract infection (URTI) is more. And viral infection is the most common cause for this.
Influenza is the most common virus causing this.
So better to follow these steps for better symptomatic relief.
1. Avoid oily and spicy food.
2. Avoid hard to chew food.
3. Drink plenty of fluids orally and keep yourself hydrated.
4. Do warm water gargles 5-6 times a day.
5. Do steam inhalation 5-6 times a day.
6. Start antihistamine and anti inflammatory drugs.
Since these drugs are prescribed medicines, you need doctor 's prescription for them.
Don't worry, you will be alright in 1 week.
