Detailed Answer:
Hello Mr. XXXXXXX
I've gone through your query in details...
I can understand your concern...

Well, the only way to ascertain whether you've bronchitis is by a clinical examination by a physician along with a Chest X-ray and Sputum microscopy and culture sensitivity analysis as part of the investigation.

As per your description, it seems like an upper respiratory tract infection (which may or may not be bronchitis). So please get yourself checked-up by your doctor and get the Chest X-ray and sputum analysis done for further evaluation.

Additionally, please refrain from having any cold beverages, extreme sour foods as they can further worsen the symptoms. Avoid going to any dusty/overcrowded places for the time being.

Always ensure to wash your hands with antibacterial hand-wash before and after handling the respiratory secretions, sputum etc. Do wear face masks whenever going outside.

Start taking steam inhalation three times daily, it'll bring some symptomatic relief.

Have plenty of hot beverages (soups, broths, hot menta tea) as they'll work as an immunity booster.

Let me know if I can assist you further.

Take Care
Kind Regards
