Ears will randomly pop and start ringing. feel pressure in my head and sometimes feel like i get kind of dizzy/unbalanced. what is this?

Ear congestion: This is a result of your nasal congestion and can cause you to be off balance. You need to treat your nasal congestion, you need to have a nasal spray. Better, see an allergist and get tested to determine your triggers and discuss long term options for your symptoms.

Eustachian : If this during air traveling or driving? If yes, this could be from eustachian tube dysfunction. Either way, you should be evaluated by a doctor or an ENT specialist.
