Thanks for the query,
Please note that MRI findings should be interpreted along with the clinical data. The MRI data that you have provided could seen in patients with diabetes, hypertension
. These changes reflect micro vascular ischemia. You donot have to worry for this changes at all.
Back to your headache. Headache can be due to various causes like migraine, cluster headache
, tension headache
, infection in the brain, brain tumor and so on. The possibility in your case could be migraine and/or tension headache. These diagnoses are that of exclusion. Further if the headache duration is only of 3 weeks, other conditions must be excluded before securing the diagnosis of migraine. Good that your MRI is normal. I advise you to get a neurological evaluation done by a neurologist
. He will then determine a lumbar puncture
will be required in your case or/not.
Management will be as per the cause
Hope this clarifies your query
