Thanks for your question on Healthcare Magic. 
I can understand your concern. 
In my opinion, you are mostly having 
migraine like headache. 
No need to worry for major brain pathology as your 
CT scan is normal. 
Follow these steps for better symptomatic relief in migraine. 
1. Drink plenty of fluids orally and keep yourself hydrated. 
2. Avoid 
stress and tension, be relax and calm. 
3. Avoid oily and spicy food. Avoid junk food. 
4. Avoid fasting and take your meals timely. 
5. Take sound sleep of 6-8 hours. 
6. Take combination of 
propranolol and 
flunarizine at night time before sleep. 
Don't worry, you will be alright if all these.. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
