After a severe burn to sinuses 6 yrs later, can feel sinus drainage into scalp and down neck, ears pop, balance issues foot numbness. What tests?

There R a few. Issues. Have u been having this issue for 6 years? How did u burn sinuses? I would see an ear nose and throat specialist but as a principle, nasal steroids would decrease inflammation, wash over eustachion tubes that drain into the back of the thrat and maybe help to drain the inner ear that mat be affecting balance.Drainage into scalp doesn't occur. Do you grind teeth at night or have insomnia?
