Hello and hope you are doing well.
It’s unlikely to be cerebrospinal fluid. It should most probably be due to an infection. This is more so as you have had a recent infection. The consistency of the fluid will depend on the type of infection. Clear discharge can also occur with allergic reaction. If it persists consult your doctor for an evaluation. You could practice good breathing exercises, humidify your room and do steam inhalations.
Hope this helped and do keep us posted.
Hi, I'm 15 and suffer from tonsillitus very badly. I get it many times a year, however even when I don't have it I have very thick, bad tasting dark yellow gunky liquid at the back of my throat which I can't get rid of. It coughs out a lot and I don't know what it is. I have very regular dental hygeine and try to take care of my mouth. I have no idea what it is and have never heard of it before. Is there anyway to get rid of it? And would I be eleigible for tonsillectomy? as it is kind of taking over my life
