What are some reasons why you would still have headaches days after hitting my head?

1. Concussion. A concussion is a traumatic brain injury (TBI) that can cause a variety of symptoms, including headaches. Concussions can occur when the head is hit hard, even if there is no visible injury. Symptoms of a concussion can include headache, nausea, vomiting, dizziness, confusion, memory loss, and sleep problems. Headaches from a concussion can last for days or even weeks.

2. Post-concussion syndrome (PCS). PCS is a condition that can develop after a concussion. PCS symptoms can include headache, fatigue, dizziness, memory problems, and sleep problems. PCS can last for months or even years.

3. Migraines. Migraines are severe headaches that can cause pain, nausea, vomiting, and sensitivity to light and sound. Migraines can be triggered by a variety of factors, including stress, hormonal changes, and certain foods and drinks. Headaches from migraines can last for days.

4. Tension headaches. Tension headaches are the most common type of headache. They can cause a mild to moderate pain that feels like a tight band around the head. Tension headaches can be triggered by stress, anxiety, or poor posture. Headaches from tension headaches can last for hours or even days.

If you are experiencing headaches days after hitting your head, it is important to see a doctor to rule out a concussion or other serious medical condition.
