Brief Answer:
consult a doctor in emergency room

Detailed Answer:
Hello XXXX,
I have gone through your question and understand your concerns.
Headache in young age is usually primary like migraine or tension type and less commonly cluster headache.
Secondary headache of acute onset with very severe nature (worst headache of life) requires evaluation for sub arachnoid haemorrhage.
In present scenario without any previous history of headache , i will advise to consult a doctor in emergency room. The examination by a doctor and investigations or treatment will be more beneficial rather than taking medications on its own.
In case of inability to contact a doctor , paracetamol or naproxen can be taken.
Hope you found the answer helpful.
Do get back with further queries.
Regards
Dr Neeraj Kumar
Neurologist
