Hello and welcome,
Thanks for your query.
I will need a little more information to be able to help you.
Like at first, do you have any other symptoms?
Any phlegm/sputum being produced, either with or without any cough? Is it white or transparent (most probably no infection) or green, yellow or blood stained (possibility of an infection)?Any fever? Or just a feverish feeling?
Based on the description you are giving me, I suspect a
dust allergy. Which is quite common.
Are you constantly exposed to dust or have you noticed these symptoms to crop up when you are exposed to dust?
If this is the case, some mild anti-histamines will help you. But then again, taking medications often is not considered to be healthy. What would be best, is to always carry a hand napkin with you, or even the use of a face mask, to protect you from dust when you visit areas with a lot of dust.
Contemplate the possibility and discuss this with your father and/or your family doctor.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
Best wishes.
