Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of viral upper
respiratory tract infection (URTI) and recurrent
bronchitis are more.
You are active smoker. And
smoking cause reduction in body defense especially respiratory tract.
So recurrent viral infection is common in smokers.
This viral infection causes URTI and bronchitis.
So better to quit smoking as soon as possible.
Drink plenty of fluids orally and keep yourself hydrated. Do warm water gargles 5-6 times a day.
Take antihistamine and anti inflammatory drugs.
Avoid oily and spicy food.
Don't worry, you will be alright with all these.
Quit smoking as soon as possible.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
