Hello and thanks for the query
You may be suffering for viral infection and frequent running nose is indication of this. Protect your self from allergens like dust, pollen and mines. Take Anti-histamines drugs like Cetirizine
to get control on the allergy
. As mucus is thick and yellow colored, you may need a course of antibiotic. In addition to this take regular steam inhalation 3-4 times a day and try to expel out mucus as much as you can.
Also protect yourself from changing weather.
Hope this will help you.
