Migraine: This condition is characterized by recurrent episodes of headaches, often accompanied by photophobia and can involve various parts of the head, including the area around the eyebrows. The pinch sensation could be interpreted as a form of aura or part of the migraine headache itself.

Tension Headache: While typically less severe than migraines, tension headaches can cause a sensation of pressure or tightness around the forehead and eyebrows, potentially described as a pinch. Photophobia can also be present, though it's less common than in migraines.
Cluster Headache: These are severe headaches that occur in cycles or clusters, often involving one side of the head and can include the eyebrow area. They are associated with autonomic symptoms like photophobia and could potentially cause a pinch-like sensation due to their severe nature.
Sinusitis: Inflammation of the sinuses can cause pain and pressure in the face, including the area around the eyebrows, especially if the frontal sinuses are involved. Photophobia can occur if the condition leads to headache or if there's associated meningismus.

Subarachnoid Hemorrhage: Although less common, a sudden, severe headache (often described as "the worst headache" of one's life) with photophobia could be indicative of a subarachnoid hemorrhage. The pinch sensation might be an atypical description of the initial hemorrhage pain.
Temporal Arteritis: This condition involves inflammation of the blood vessels in the head and can cause headaches, scalp tenderness, and visual disturbances, including photophobia. It's crucial to consider this diagnosis, especially in older adults, due to the risk of vision loss if not promptly treated.
Meningitis: Inflammation of the protective membranes covering the brain and spinal cord can cause headache, photophobia, and neck stiffness. While the pinch sensation in the eyebrow might not be a classic symptom, the combination with photophobia warrants consideration of this potentially life-threatening condition.

Trigeminal Neuralgia: This condition involves sudden, severe, shock-like or stabbing pain in parts of the face, which could potentially include the area around the eyebrows. While photophobia is not a primary symptom, the pain can be so severe that it might lead to sensitivity to light.
Occipital Neuralgia: Involves inflammation of the occipital nerves and can cause pain in the back and side of the head, potentially radiating to the eyebrow area. Photophobia might not be a direct symptom but could be associated if the condition triggers migraine-like symptoms.
Idiopathic Stabbing Headache: Characterized by brief, sharp pains or stabs of pain in the head, which could be described as a pinch sensation. These headaches can occur anywhere in the head, including the eyebrow area, and might be accompanied by photophobia in some cases.
