Hi, thanks for using healthcare magicPost nasal drip
is usually part of allergic sinusitis
. It can be associated with sore throat
The treatment is normally as prescribed by your doctor- nasal sprays. Antihistamines can also be used. It would also be important to avoid whatever allergen is provoking the allergies.
In terms of the colour of the mucus, it may indicate an infection either viral or bacterial. If it persists then you may want to be evaluated by your doctor.
I hope this helps
