Recovered from bacterial meningitis 3 yrs ago. sinuses were 100% blocked. doc says after meds they look better/cleaned out. can it happen again?

Confusing post: Do you mean you had a sinus infection recently & are worrying about meningitis ? There are dozens of germs that can cause meningitis & it rarely happens more than once. The germ can enter from the nasal passages, but a sinus infection by itself does not predispose to meningitis. This is something better discussed with the doc who has all your records & knows your immune status.
