Are there any major nerves by your eyebrow?

Yes, there is a major nerve near the eyebrow called the supraorbital nerve.

The supraorbital nerve is a branch of the trigeminal nerve (cranial nerve V).

It provides sensory innervation to the scalp, forehead, and upper eyelid.

The supraorbital nerve emerges from the skull through a small opening called the supraorbital notch or foramen, located just above the eyebrow.

It then divides into multiple branches that spread out over the forehead, scalp, and upper eyelid.

The supraorbital nerve is responsible for sensation, including pain, touch, temperature, and pressure, in the areas it supplies.

Damage to the supraorbital nerve, such as from injury or compression, can result in numbness, tingling, pain, or other abnormal sensations in the forehead, scalp, or upper eyelid.
