Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and would like to reassure you that these are suggestive of tension headache and there is no need to worry. A normal CT scan last times ensures that there is no serious cause of headaches.
I hope it helps. Please get back if you have any follow up queries.
