Brain hemorrhage causes patients to have headaches that mostly occur suddenly and are very severe. If the hemorrhage is in the cerebellar region, it will cause a severe headache in the back of the patient’s occipital region, which can manifest as blast-like pain. In addition to the headache, the patient will also have jet-like nausea, vomiting, unstable walking, and balance disorder. If the hemorrhage is in the brain tissue, the patient will also have headache symptoms, but it will manifest as dysfunction of the lateral limbs or loss of consciousness, and the patient’s vital signs are unstable, which are all concomitant symptoms of brain hemorrhage headache. In the case of subarachnoid hemorrhage, which usually occurs when the patient is active, emotionally agitated, or exerted, the patient has a very intense headache with unbearable pain, and the patient feels as if the headache is about to explode.
