I have heavy pain in both side of my head that causes dizziness, sometimes in my back and neck?

I am female and 40 years old and my headache started when i gave birth to my daughter 5 years ago, that time it was only severe headache and I was using relieve tablets to get rid of the pain but every since it got worse, and now the heavy pain is in both side of my head that causes dizziness, sometimes my back and neck i feel vomiting, loud sounds make it worse and it lasts for one day mostly.
i went to doctors , they gave me tablets and told me its nerve disease and its because you get emotional.
it didn’t work even it got worse so i stop using them…please advise what I should do next?
