Brain hemorrhage headache lasts for about 2-3 weeks. Brain hemorrhage headache is mainly caused by the intracranial occupancy effect after brain hemorrhage, which leads to the headache caused by the increase of intracranial pressure. As the headache is mostly caused by the increase of intracranial pressure, the headache will be relieved after the condition is gradually stabilized and the intracranial pressure is better controlled. The headache is mainly related to the edema of the surrounding tissues after brain hemorrhage, and secondly, it is caused by the blood breaking into the subarachnoid space after brain hemorrhage. Generally, the cerebral edema will gradually subside in about 2-3 weeks, and the blood that has broken into the subarachnoid space will be absorbed gradually, so the headache will be relieved gradually, and its duration will be about 2-3 weeks. In order to treat headache, the early stage is mainly to use dehydration and cranial pressure lowering drugs. If the intracranial pressure is not high and is caused by the irritation of bloody cerebrospinal fluid, lumbar puncture can be performed to release the cerebrospinal fluid for treatment, and pain medication can be taken at the same time.
