Storm/screen door fell and hit me in back of head.plexy glass hit & my ears rang. i feel ok, bit shook up, but do i need to watch for anything or ok?

The most important: question following an episode like this is "Did you lose consciousness?" If so, an evaluation with a doctor/health professional is needed. If not, and you feel ok, you should still watch for: headache, drowsiness, confusion, nausea, vomiting, dizziness, imbalance, blurred or double vision, decreased hearing, blood or clear fluid from nose or ear. Hopefully all will be well; good wishes:)
