If you have suffered from a debilitating headache that prevented you from going about with your day, you are not alone. Statistical data suggests that headaches affect 16.5% of the population each year. Headaches are often accompanied by symptoms affecting other body parts, including the eyes and the stomach. While headaches are often not severe and can be cured with proper care, some early warning signs of the condition should not be ignored. Nausea and vomiting Nausea, vomiting, and digestive problems are common indicators of migraine headaches. These signs and symptoms often develop before a migraine attack and are called “aura.” Therefore, it is important to understand the underlying cause of a migraine, which can help doctors prescribe a suitable treatment course. Hence, one must consult a doctor immediately in case of migraine signs and symptoms like nausea and vomiting. Fever and body stiffness Patients with meningitis or encephalitis typically develop fever, body stiffness, and blinding headaches. Encephalitis refers to an inflammation of the brain, whereas meningitis is characterized by inflammation of the membrane surrounding the brain. Such inflammation may trigger flu-like symptoms. Individuals experiencing headaches along with fever and body stiffness must seek a doctor’s guidance at the earliest.
