One of the worst pains Migraine. And in the context of headaches, it "stands apart". And this is not just pain - a migraine is an independent disease. But why then does this pathology arise? For quite a long time, medicine had no answer to this question, but nothing stands still - now the cause is known. It's about the increased excitability of nerve cells. They make the vessels dilate, to which the pain receptors of the vessels themselves react. And a strong unilateral pulsating pain appears, which is exactly how migraine manifests itself.
