Would sinuses allergies make your head funny every day for 8 years and sometimes cause weird head feeling like brain zaps or swaying i do have anxiety?

Doubtful: These symptoms are not characteristic of chronic paranasal sinus congestion or infection, but with chronic nasal congestion the eustachian tube, which runs from the back of the nose to the middle ear, can cause a sense of imbalance. I recommend consulting a psychologist or psychiatrist for stress management therapy. You could also have an evaluation by an Otolaryngologist for peace of mind as well
