There are several reasons for brow pain: 1. Skin surface causes, if there are small bumps and small cysts infected on the skin surface, it may cause pain at the brow. If there are no small bumps at the brow location consider frontal sinusitis, frontal sinusitis may have obvious pain in the morning and gradually have symptoms of relief in the afternoon, frontal sinusitis can have obvious pressure pain at the brow. If you want to further clarify whether it is caused by sinusitis, you need to do further sinus CT examination or even nasal endoscopy to see if there are new organisms or purulent secretions coming out of the nasal cavity. 2, vascular neurological headache, this kind of neurological headache can not find a clear cause by CT or nuclear magnetic examination, and there is no obvious local pressure pain, sometimes you need to use pain medication or do physical therapy to relieve the symptoms of headache. 3. Intracranial lesions, such as intracranial masses and intracranial hemorrhage, may also cause pain in the brow, but such cases are rare.
