hello welcome to healthcaremagic.
i understand your concern and will try my best to help you out.
see the tight hat can never cause any
brain damage be assured of that.
however since you are experiencing some symptoms, the root cause has to be evaluated.
i would advice you to get following investigations done-
1.MRI BRAIN.
2.CECT HEAD.
3.EEG
also i would like to know some history like
history of migraine/any other headache in self/family.
history of TIA or stroke
history of
hypertension diabetes thyroid disorders
history of any other endocrine disorders
the most probable explaination for your symptoms was a headache. so i would advice you to take an nsaid like
naproxen.
also please follow up with the nearby doctor asap.
i hope this helps.
please feel free to revert back in case of any further doubts/ concerns
i hope for your good health
thank you
