Headache?

Whenever I start to get a headache, it becomes so severe that I feel like I might vomit.

But whenever I feel a little tired, I inevitably get a headache... So, I tend to have headaches more often than others.

And now, I think it has become chronic enough that even taking painkillers is necessary for them to be effective.

At first, I didn't know and just endured, but then I was so overwhelmed that I suffered a lot. Now, whenever I feel a slight discomfort, I take an anti-inflammatory painkiller immediately and fall asleep right away.

Should frequent headaches be referred to a neurologist?

Is there a good place in Daegu?

Please recommend.
