Re: yellow linquit coming from the noise
It is probably sinus drainage due to an allergy. If it is a light yellow, use saline solution to irrigate the sinuses and take an anahistamin, such as Zyrtec (prescription). If it is a dark yellow, this is an indication of an infection.
Best to see a doctor if irrigation and anahistamin does not work.
