Headaches are extremely common in the general population, so much so that most of us don’t even bother to think about what could be causing it. And while usually, headaches aren’t something to worry about, they could sometimes be a symptom of a serious underlying condition. Catching some diseases early can be the difference between a good and a bad outcome, so make sure you get a check-up if you’re experiencing headaches that are recurrent or very severe. Headaches can occur in people of all ages and be of many different types.
