Hello, I have taken note of your problems in detail. .
Since your CT Scan
is normal a major structural lesions in brain is ruled out..
Regarding your epistaxis
I would suggest you to undergo a specialist ENT check for any bleeders inside nose or any nasal spur which can cause recurrent epistaxis. .
Regarding light headedness I would suggest you to undergo go blood test
for Hb% hemoglobin
and cardiac evaluation with ECG and consult a a physician/cardiologist for detailed examination. ..The cause for light headedness can vary from simple anemia to heart disease
and autonomic dysfunction. ..
Wish you speedy recovery, any further information on the this will be glad to answer
