Thank you for posting your query.
I have noted your symptoms. First of all, I would like to reassure you that there is no need to worry, as your symptoms do not suggest any serious brain injury
Your passing out could be due to syncope (on account of reduced blood flow to brain related to severe pain
Your current symptoms are part of concussion
and you would get better in a few days.
As of now, you can take symptomatic treatment with ibuprofen (for headache) and betahistine
I hope my reply has helped you.
I would be pleased to answer, if you have any follow up queries or if you require any further information.
