Been coughing up mucous and a running nose for about a month and for 2 weeks my ears started to feel full and with a high pitch ring what is this?

Upper respiratory : You should be evaluated for allergies, and get a good explanation of possible causes, like environmental, animals, etc. Many patients have "cough variant asthma", not classic "wheezing". A sinus infection can occure in inflamed nasal and sinus tissues, which often requires care which can't be done with otc meds. Mucous may cover the tube in the throat leading to ear symptoms and ringing.
