Why Does My Forehead Hurt When I Touch It?

Forehead tenderness when you press on it usually traces back to one of a handful of common causes: a tension headache tightening the muscles and skin around your skull, a migraine triggering unusual skin sensitivity, inflamed sinuses pressing against the bone behind your brow, sunburn, or irritation of one of the small nerves that runs across your forehead. Less commonly, infections like shingles, nerve-specific conditions, or referred pain from the neck can be responsible. The forehead is one of the most nerve-rich areas of the face, which is part of why even minor issues there can produce surprisingly sharp discomfort.

Why the Forehead Is So Sensitive in the First Place

The skin of your forehead gets almost all of its sensation from a single source: the first division of the trigeminal nerve, known as V1. This is the smallest of the trigeminal nerve’s three branches, and it is purely sensory, meaning its only job is to relay feeling. It covers the forehead, the eyebrows, the upper eyelids, parts of the nose, and even internal structures like the frontal sinus lining and portions of the membranes around the brain.¹ Because this nerve is packed densely into a relatively small area of skin stretched over bone with very little cushioning fat or muscle, even modest inflammation or pressure can register as pain when you touch the area.

Two specific branches of V1 are worth knowing about. The supraorbital nerve exits through a small notch or hole in the bone just above each eyebrow and fans upward across the forehead. The supratrochlear nerve runs closer to the midline, near the bridge of the nose. When either of these nerves is irritated, compressed, or caught up in nearby inflammation, the result is localized forehead pain that often gets worse with touch or pressure.

Migraine and Skin That Hurts to Touch

One of the most common reasons a forehead becomes painful to the touch, even when there is no visible injury, is a phenomenon called cutaneous allodynia. In plain terms, this means that stimuli that should not hurt (a light touch, combing your hair, resting your head on a pillow) suddenly do. It is remarkably common during migraine attacks, and researchers have tracked how it develops in real time.

In a detailed case study, researchers measured pain thresholds at multiple points during a migraine attack and found a clear progression. Within the first hour, the skin on the same side of the head as the migraine became sensitive to touch and cold. By two hours, that sensitivity spread to the opposite side of the head and even down to the forearm on the migraine side. By four hours, heat sensitivity had joined the picture, and the skin tenderness kept intensifying.² This spreading pattern suggests that the pain system essentially ramps up in waves, first locally and then more broadly, as deeper relay stations in the brainstem and brain become sensitized.

If you get migraines frequently (more than fifteen days per month), this skin sensitivity can become more or less constant rather than coming and going with individual attacks. A study of people with chronic migraine found that about 43% had measurable skin allodynia even when they were not in the middle of a full-blown migraine episode, and the sensitivity was most common on the head and neck.³ In children and adolescents with migraine, roughly a third report forehead-area skin pain, with higher rates in those who experience aura before their headaches.⁴

If you notice that your forehead only hurts to the touch during or shortly after a headache, and the tenderness fades between episodes, migraine-related allodynia is a strong candidate. People sometimes think the sore spot is a bruise or a bump they do not remember getting, when it is actually their nervous system turning up the volume on normal touch signals.

Tension Headache and Pericranial Tenderness

Tension-type headache is the most common headache worldwide, and one of its hallmarks is tenderness of the muscles and tissues around the skull, a finding doctors call pericranial tenderness. When you press on your forehead, temples, or the back of your head during a tension headache, the muscles and overlying skin often feel sore in a way that seems out of proportion to the pressure you are applying.

A population-based study found that people with chronic tension-type headache consistently had elevated pericranial tenderness scores compared to people without headaches, and that younger people and those who also experienced migraines tended to have the highest tenderness.⁵ Research in children with tension-type headache showed a similar pattern: tenderness scores were significantly elevated across all tested sites on the head compared to controls.⁶

What makes tension headache tenderness different from migraine allodynia is the mechanism. In tension headache, there is evidence that the body’s built-in pain-dampening system is not working as well as it should. Research found that in people with frequent episodic tension-type headache, endogenous pain modulation processes are compromised, which could make them more vulnerable to both scalp tenderness and recurring headache episodes.⁷ In other words, the problem is not so much that the forehead muscles are damaged, but that the brain’s natural pain filter is letting through signals it would normally suppress.

Sinus Infections and Frontal Sinusitis

Your frontal sinuses sit directly behind your forehead, just above the inner corners of your eyebrows. When they become inflamed or infected, the pressure and swelling push outward against the thin bone, producing a deep ache that intensifies when you press on the area, lean forward, or bend over. A sinus-related cause is especially likely if you also have nasal congestion, thick discolored mucus, reduced sense of smell, or facial pressure that worsens through the day.

Most frontal sinus infections resolve with time or antibiotics, but in rare cases the infection can erode through the bone and cause a soft, tender swelling on the forehead known as Pott’s puffy tumor (which is not actually a tumor but a subperiosteal abscess). Patients with this complication present with tender forehead swelling with pitting edema, and it constitutes a surgical emergency.⁸ This is extremely uncommon, but if you have forehead pain with visible swelling, fever, and a worsening sinus infection, get medical attention promptly.

Supraorbital Neuralgia and Other Nerve-Specific Conditions

Sometimes the problem is not the muscles, sinuses, or headache system at all but a single small nerve. Supraorbital neuralgia involves irritation or entrapment of the supraorbital nerve right where it exits the skull above the eyebrow. It is relatively rare, accounting for about 4% of trigeminal neuralgia cases, but it has a recognizable pattern: localized pain in or above the eyebrow in the territory of the supraorbital nerve, tenderness when you press on the supraorbital notch (the little dip in the bone above the inner eyebrow), and complete but temporary relief when the nerve is blocked with a local anesthetic.⁹ People sometimes notice this after wearing tight helmets, headbands, or goggles that press against the nerve exit point for prolonged periods.

Another condition worth knowing about is nummular headache, which produces a mild-to-moderate pressure-like pain felt exclusively in a small rounded or oval area, typically about two to six centimeters across. Although it most often appears on the side or top of the head, it can occur on the forehead. The affected spot stays fixed in the same location and does not change shape over time.¹⁰ If you can outline the painful area with your finger and it always feels like the same coin-sized patch, this is a possibility to raise with your doctor.

A third localized cause is trochleitis, inflammation of the trochlea, a small pulley-like structure in the inner upper corner of the eye socket through which one of the eye muscles passes. When inflamed, it causes pain in the inner brow area and upper forehead that can be reproduced by pressing on the spot. It sometimes exists alongside migraine or tension headache, and it may go unrecognized when a doctor attributes all the pain to the headache disorder itself.¹¹

Shingles on the Forehead

Herpes zoster (shingles) can reactivate along any nerve, but when it follows the first division of the trigeminal nerve, the rash and pain appear on the forehead, upper eyelid, and sometimes the tip of the nose. Before the rash becomes visible, many people notice burning, tingling, or exquisite tenderness in the skin, and pressing on the area feels disproportionately painful. This prodromal pain can precede the blisters by several days, which makes it easy to mistake for a tension headache or sinus problem until the characteristic rash shows up.

After the rash heals, some people develop postherpetic neuralgia, a persistent nerve pain that can last months or even years. Risk factors for this complication include older age, severe pain during the initial outbreak, a widespread rash, the presence of prodromal pain before the rash appeared, and having a weakened immune system.¹² If you are over 50, vaccination significantly reduces the risk of both shingles and postherpetic neuralgia.

Sunburn and Other Skin-Level Causes

Not every case of forehead tenderness involves nerves or headaches. The forehead is one of the most sun-exposed surfaces on your body, and even a modest sunburn there produces pain on touch that can catch you off guard, especially if you did not notice the burn developing. Research on UVB-induced skin inflammation shows that the peak pain sensitivity from sunburn typically hits between 24 and 48 hours after exposure and can remain detectable for at least 72 hours.¹³ So if your forehead hurts to the touch a day after being outdoors, sunburn is the simplest explanation, even if the redness seems mild.

Other skin-level culprits include cystic acne (deep, painful bumps under the skin that are especially common along the hairline and forehead), contact dermatitis from a new shampoo, hair product, or hat material, and insect bites that have become inflamed. These are usually straightforward to identify because you can see or feel a localized change in the skin itself.

When the Pain Comes From Your Neck

This one surprises people: problems in the upper neck can produce pain that you feel in the forehead. The explanation lies in how the nerves from the upper cervical spine converge with the trigeminal nerve’s pathways in the brainstem. Signals from the upper neck and signals from the face share processing space, which means the brain can misattribute neck-origin pain to the forehead. This overlap “explains the spread of pain from occipital to orbital or frontal regions,” and it is why cervical pathology can mimic pain that seems to come from the face.¹⁴

Cervicogenic headache is the formal name for this pattern. It often starts at the back of the head or neck and radiates forward to the forehead or around the eye. The forehead skin may feel tender to the touch, but the actual trigger is a stiff or injured joint, disc, or muscle in the upper cervical spine. A clue that your neck is involved: the forehead pain changes when you move your head into certain positions, or a physical therapist can reproduce the forehead tenderness by pressing on specific spots in your upper neck.

Giant Cell Arteritis and Other Red Flags

Most causes of forehead tenderness are benign, but there are a few situations where the symptom deserves urgent attention. Giant cell arteritis (GCA) is an inflammatory condition of blood vessels that almost exclusively affects people over 50. It typically involves the temporal arteries at the sides of the head, but it can affect any cranial artery. Classic features include a new headache, scalp tenderness (it may hurt to brush your hair or rest your head on a pillow), jaw pain with chewing, and visual disturbances. Thickness and tenderness of the temporal arteries are the most recognizable signs on physical examination.¹⁵ GCA requires prompt treatment with corticosteroids because it can cause permanent vision loss if the blood supply to the optic nerve is compromised.

Other situations that warrant a prompt medical visit include forehead tenderness accompanied by fever and visible swelling (possible complicated sinus infection), a new rash with blisters on one side of the forehead (shingles involving the eye area, which can threaten vision), sudden severe headache unlike anything you have experienced before, and forehead pain after a head injury that is worsening rather than improving.

Stress, Sleep, and Emotional Factors

Psychological stress does not cause forehead pain in the way that an infection or a compressed nerve does, but it powerfully modulates how much pain you feel. Chronic stress increases muscle tension in the scalp and forehead, lowers pain thresholds, and can perpetuate the cycle of tension-type headache and pericranial tenderness. Research into psychogenic headache has found that headache occurring against a background of constant emotional stress affects a large majority of patients with neurasthenic disorders, often intensifying toward the end of the workday and accumulating through the work week. Poor sleep has a similar amplifying effect: it reduces the brain’s ability to dampen incoming pain signals, which is the same impaired modulation pathway implicated in tension headache tenderness.

If your forehead seems to hurt to the touch mainly in the evenings, on high-stress days, or after nights of poor sleep, the tenderness is likely a physical manifestation of central nervous system changes driven by these factors rather than a sign of structural damage.

Treatment Approaches That Target Different Causes

Because forehead tenderness has so many possible origins, treatment depends entirely on the underlying cause. For migraine-related allodynia, taking your acute migraine medication early, before the skin sensitivity fully develops, tends to be more effective than waiting. Once central sensitization is established (usually within the first couple of hours of an attack), the allodynia can become self-sustaining and harder to reverse. Preventive migraine treatments that reduce attack frequency also tend to reduce allodynia over time.

For localized nerve pain such as supraorbital neuralgia, targeted nerve blocks can be both diagnostic and therapeutic. Research has found that combined blockade of the greater occipital nerve and the supraorbital nerve provides better outcomes than blocking the occipital nerve alone, with greater improvements in pain scores, sleep quality, and psychological well-being in people with chronic migraine.¹⁶ A separate study confirmed that both nerve block approaches reduced pain frequency and painful days compared to baseline, with the blocks producing lower pain intensity scores than oral medication alone.¹⁷

For tension-type headache tenderness, over-the-counter pain relievers help with individual episodes, but if the problem recurs frequently, physical therapy targeting the neck and pericranial muscles, stress management, and sometimes low-dose preventive medications address the underlying central sensitization more effectively than painkillers alone. Sinus-related forehead pain responds to decongestants, nasal irrigation, and, when bacterial infection is confirmed, antibiotics. Sunburn-related tenderness needs cooling, moisturizing, and time.

Sorting Out the Cause Yourself

You can narrow down the likely culprit by paying attention to a few details. Ask yourself where exactly the tenderness is: a single fixed spot the size of a coin (think nummular headache or nerve entrapment), the entire forehead and scalp (more consistent with migraine allodynia or tension headache), or directly above the inner eyebrow (supraorbital nerve or trochleitis). Notice when it happens: only during or after headaches (allodynia), after sun exposure (sunburn), during a cold with congestion (sinusitis), or steadily worsening over days with a rash appearing (shingles).

Consider what makes it worse. If bending over intensifies the pain, sinus involvement is more likely. If neck movement changes it, referred cervicogenic pain is a good bet. If it gets worse as the day and the stress wear on, tension-type headache is the leading candidate. And if you are over 50 with a new headache that involves scalp tenderness and any change in vision, skip the self-assessment and see a doctor that day.
