I fainted last friday and suffer from very bad headaches, fainting is also regular occurrance and very uncomfortable for me, ive had a ct brain scan negative, blood tests negative so whats causing this??????
As a CT and blood work have ruled out other causes, it's possible that you have high or low blood pressure.
If your fainting (syncope) and headaches occur mostly after standing then you could have orthostatic hyper of hypo tension (high or low blood pressure after standing up).
Ask for your blood pressure to be checked (also ask for diabetes and anaemia tests if you haven't already had them).
If this has only started happening during the recent warm weather, it may be heat stroke. You should ask your doctor about this as well as the suggestions above.
