Hi Sandrarh,

Welcome to the NeuroTalk Support Groups.

I would suggest seeing a doctor.
I believe it's better to err on the side of caution with any head injuries.

Don't drink alcohol and if you're taking pain killers, take something like paracetamol rather than aspirin or ibuprofen.
Don't drive a car.

visible trauma to head,

alcohol intoxication,
