Yes, there is a significant relationship between concussions and headaches. A headache is one of the most common symptoms following a concussion, often described as a "pressure" or "pounding" in the head. This post-traumatic headache can appear within seven days of the head injury or after regaining consciousness and can last for varying lengths of time, sometimes even up to a year or more if a person develops post-concussion syndrome. It's important to monitor headaches after a concussion because a worsening headache might signal a more serious brain injury. A healthcare provider can help manage post-concussion headaches and determine if further evaluation or treatment is needed.
