What causes a dull ache in back of head?

There are many possible causes for a dull ache in the back of the head, including:

* Tension headaches: These are the most common type of headache, and they can cause a dull, aching pain in the back of the head, neck, and shoulders. Tension headaches are often caused by stress, anxiety, or depression.

* Migraines: Migraines are severe headaches that can cause a variety of symptoms, including a dull ache in the back of the head, nausea, vomiting, and sensitivity to light and sound. Migraines are often triggered by certain foods, stress, or hormonal changes.

* Sinusitis: Sinusitis is an inflammation of the sinuses, which are located around the nose and eyes. Sinusitis can cause a dull ache in the back of the head, as well as facial pain, congestion, and a fever.

* Cervicogenic headaches: These headaches are caused by problems with the neck, such as a herniated disk or arthritis. Cervicogenic headaches can cause a dull ache in the back of the head, as well as neck pain, stiffness, and dizziness.

* Other medical conditions: A dull ache in the back of the head can also be a symptom of a number of other medical conditions, such as high blood pressure, diabetes, and thyroid problems. If you have a dull ache in the back of your head that is severe or does not go away, it is important to see a doctor to rule out any underlying medical conditions.

In most cases, a dull ache in the back of the head is not a serious condition and will go away on its own. However, if you are experiencing any other symptoms, such as nausea, vomiting, or fever, it is important to see a doctor to rule out any underlying medical conditions.
