Evaluate your ability to carry out daily activities despite the presence of your headache. While tension headaches can be distressing and disruptive, many individuals are able to power through and maintain their productivity, successfully navigating their work, driving, reading, and fulfilling their daily obligations. Migraines, however, often demand a different approach, as they tend to be incapacitating, necessitating retreat to a dimly lit, quiet room adorned with a sleep mask until the storm subsides. If your headache significantly impairs your functional capacity, it is a strong indication of a migraine.
