Hi,
Thank you for posting your query.
I have noted your symptoms.
Any new onset headache needs to be evaluated, especially in your case, as it has lasted about three weeks already.
MRI is the investigation of choice, as it can show all likely pathologies, such as lack of blood flow, infection, etc.
If MRI comes out as normal, then, you would need treatment for
migraine.
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.
Best wishes,
