Left frontal subcortical ischemic focus otherwise normal brain mri exam" kindly which medication can cure this. i feel pain at the top of head whenever i speak and walk mostly in the evenings?

None : At your age this is a non specific finding of no importance Check blood pressure and have a check up for blood sugar etc Certainly not responsible for headache !

Coincidental finding: The described "focus" is NOT the cause of head pain, and does not represent an ongoing threat. This may represent a congenital lesson or result of prior trauma. Suggest you discuss your current issues with your doctor and devise a plan to enhance future health and well-being. Do not worry about MRI report.
