How do i fix my headache?

A good start would be to write down all of your related symptoms/time frame/duration/intensity/location/past efforts to treat/etc. . You then take the list with you for an evaluation that includes a past/current medical history, travel history, exam and possibly testing. When you have the range of information in place a proper plan for treatment can be formulated. A post without the data won't do

First step is to classify the headache. A neurologist would be key, and important to understand underlying triggers. Migraine can be handled very well these days. A headache diary will assist greatly and many doctors and patients can interact efficiently to deal with the triggers. But uncover mechanisms and find out what is main issue.
