Disease description:

Two days ago, I tried to lie down on a wooden board but lowered myself too quickly, hitting the back of my head. At that moment, I felt dizzy and had pain at the back of my head. Yesterday, I didn't feel anything at all, but this afternoon the pain in the back of my head suddenly returned. What could be causing this sudden pain in the back of my head?

Sudden pain in the back of the head may be caused by biological factors or brain disorders. Such pain could be related to intense anger or elevated blood pressure. Prolonged熬夜 (staying up late) or severe sleep deprivation may trigger headaches. If headache is accompanied by dizziness, numbness or weakness in the limbs, it may indicate a cerebrovascular disease.
