Differential Diagnosis for Pain in the Back of the Head
Single Most Likely Diagnosis
- Tension Headache: This is the most common type of headache and often presents with a band-like pressure or aching sensation in the back of the head and neck, typically due to muscle tension.
Other Likely Diagnoses
- Cervicogenic Headache: Originates from the cervical spine and is often caused by poor posture, neck strain, or cervical spondylosis, leading to pain in the back and side of the head.
- Occipital Neuralgia: Involves irritation or inflammation of the occipital nerves, causing sharp, stabbing pain in the back of the head and sometimes extending to the scalp.
- Migraine: Although migraines often present with unilateral pain, they can sometimes cause pain in the back of the head, especially if the migraine is in its prodromal phase or if it's a basilar-type migraine.
Do Not Miss Diagnoses
- Subarachnoid Hemorrhage: A life-threatening condition caused by bleeding into the space surrounding the brain, which can present with sudden, severe headache (often described as "the worst headache of my life") and may initially be localized to the back of the head.
- Meningitis: Inflammation of the protective membranes covering the brain and spinal cord, which can cause severe headache, fever, and stiff neck, with the headache sometimes being more pronounced in the back of the head.
- Cervical Artery Dissection: A tear in the wall of one of the arteries in the neck, which can lead to stroke and may initially present with pain in the back of the head or neck.
Rare Diagnoses
- Giant Cell Arteritis: An inflammatory condition affecting the blood vessels, particularly those in the head, which can cause headaches, including pain in the back of the head, along with other symptoms like jaw claudication and visual disturbances.
- Chiari Malformation: A structural defect in the cerebellum that controls balance, which can cause headaches, often in the back of the head, due to the pressure on the brain and spinal cord.
- Eagle Syndrome: A condition caused by an elongated or calcified styloid process, which can irritate nearby nerves and cause sharp, stabbing pain in the back of the head and face.
