Migraine vs. Headache: Differences and Similarities
Headaches are the most common reason why a person goes to the doctor or other healthcare professional for treatment. There are different types of headaches, for example, migraine, tension, and cluster headaches. The most common type of headache is tension headache. Migraine is much less common. There are few similarities between migraine and other headaches, for example, the severity of the pain can be the same, mild, moderate, or severe; and they can occur on one side or both sides of the head. However, there are many differences between migraine and other types of headaches. Migraine headaches also have different names, for example, migraine with aura and menstrual migraine. Symptoms of migraine that usually aren't experienced by a person with another type of headache include nausea, vomiting, worsens with mild exercise, debilitating pain, eye pain, throbbing head pain. Migraine trigger include light, mild exercise, strong smells, certain foods like red wine, aged cheese, smoked meats, artificial sweeteners, chocolate, alcohol, and dairy products, menstrual period, stress, oversleeping, and changes in barometric pressure. Untreated migraine attacks usually last from 4 to 72 hours, but may last for weeks. Most headaches resolve within 24-48 hours. Doctors don't know exactly what causes migraine headaches; however, other headaches like tension headaches have more specific triggers and causes. Additional tests usually are required to diagnose migraine from other types of headaches, diseases, or other medical problems. Most headaches can be treated and cured with home remedies like essential oils, massage, and over-the-counter pain medication like acetaminophen (Tylenol) and NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen (Aleve, Anaprox, Naprosyn) or ibuprofen (Advil, Midol, Motrin). Most headaches resolve with OTC and home remedy treatment, while your doctor may need to prescribe medication to treat your migraines. If you have the "worst headache of your life," seek medical care immediately.
