<s>[INST] My soft palate/back of my nose has been getting dry, with a small amount of mucous (yellow-ish). I have no symptoms of an upper respiratory tract infection other than waking up with some mucous in the back of my nose/soft palate, and a little bit in my throat. [/INST] Hi Dear !! Thanks for your query to Chat Doctor. Read and reviewed your query and health concerns. You seem to suffer from -Post-Nasal pharyngitis with yellow phlegm. This is not the symptom of Lower respiratory/ or respiratory infections. This is localized infection with inflammation-which makes pharynx more Chat Doctor.  So proper care of the pharyngeal and soft palate health, by gargles and cleaning with antiseptic-listerin gargles. Plenty of fluids and steaming of the respiratory passages would help it to recover fast. Tab Motrin-1 x 2 times a day-would recover this upper pharyngitis fast. Antibiotics may be added if things don't recover in 2 days time. Hope this would help you to plan further care of this complex illness of yours.
