Thanks for writing your query.
After reading your post, it seems that you are experiencing your symptoms due to high blood pressure
I would suggest that you should get yourself clinically examined by your doctor and get proper investigations done.
Following investigations will be helpful :-
1. Lipid profile
4. CT/MRI of head.
You should take antihypertensive medicines after discussing with your doctor.
Follow salt restricted diet.
Avoid strenuous physical activities.
I hope this is helpful to you.
