Visual disturbances, often described as flashing lights, zigzag lines, or temporary blind spots, can sometimes precede a headache. These experiences are commonly referred to as an "aura." An aura typically develops gradually over several minutes and usually lasts for less than an hour, often before the headache pain begins. Doctors usually inquire about the specific nature of these visual changes, their duration, and whether they affect both eyes or just one. They also want to know if other sensory changes, like tingling, occur. It's important to mention any new or worsening visual symptoms. Urgent care is needed for sudden vision loss, double vision, or if these symptoms appear with the "worst headache of your life." What did you learn about your visual changes?
