I am feeling very weird sensation when i wake up,i am feeling like something like rubbery mucus has sticked in my throat or behind voice box. I had post nasal drip before and i had consulted an ENT specialist for this,i also dont have any allergies.so what this type of mucus discharge indicates? I had done CT before 2 months and it was :Minimal mucosnal thickning in right maxillary sinus with patent biliteral omc,both fronto and ethmoidal sinuces".i had taken ENT treatment for this but didnt got full satisfaction.i also used Netipot for 7 days. Current i have nasal obstruction now.can nasal obstruction cause rubbery like mucus?
