Localized scalp tenderness is a recognized symptom of COVID-19, affecting a significant number of patients during and after infection. In one international survey of COVID-19 patients, roughly 58% reported scalp pain (a condition called trichodynia), and it frequently appeared alongside other neurological symptoms like loss of smell and taste. The tenderness you’re feeling in one spot likely stems from the virus triggering inflammation in your nerves, hair follicles, or the tiny blood vessels that supply your scalp.
How COVID Causes Scalp Pain
COVID-19 doesn’t just attack your lungs. The virus has a well-documented ability to affect the nervous system, and your scalp is densely packed with nerve endings. There are several overlapping ways the infection can produce that sore, tender feeling in a specific area.
The first involves direct nerve irritation. The virus can invade cranial nerves, particularly the trigeminal nerve, which carries sensation across much of your head and face. The receptor the virus uses to enter cells (ACE2) is present in the nerve clusters that relay pain signals from your scalp. Once the virus reaches those nerve endings, it can alter how they process pain, essentially turning up the volume on normal sensations. This is the same mechanism behind the loss of smell and taste that many COVID patients experience, just affecting different branches of the same nerve network.
The second pathway is inflammatory. COVID triggers a flood of immune signaling molecules, including IL-6, which is one of the earliest inflammatory markers to rise during infection. These molecules don’t stay confined to your respiratory system. They circulate throughout your body and can cause localized inflammation wherever they concentrate. In the scalp, this inflammation can irritate nerve endings and produce pain in a specific area, especially where blood vessels or nerves are closer to the surface.
A third possibility involves tiny blood clots. COVID activates the body’s clotting system and depletes proteins that normally prevent unwanted clotting. Researchers have proposed that microclots can form in the small vessels feeding hair follicles, cutting off blood supply to a small area of scalp. This localized damage could explain why the tenderness often hits one particular spot rather than spreading across the whole head.
The Connection to Hair Shedding
If you’re noticing more hair falling out alongside the scalp tenderness, the two are likely related. In the same international survey, scalp pain and hair shedding appeared together in about 42% of COVID patients who had either symptom. The inflammatory chemicals that cause tenderness also push hair follicles out of their growth phase prematurely. In milder COVID cases, this leads to a delayed wave of hair shedding (typically starting two to three months after infection). In more severe cases, the inflammatory assault is intense enough to damage follicles during their active growth phase, causing earlier and more noticeable hair loss.
The scalp pain often precedes or accompanies the shedding, so tenderness in one spot could be an early sign that follicles in that area are under stress. This type of hair loss is generally temporary, with regrowth beginning once the inflammation subsides.
Why It Feels Localized
Pain concentrated in a single spot rather than spread across the scalp often points to nerve involvement. Cranial neuralgias, which are bursts of pain along a specific nerve’s territory, are a known complication of COVID. The most relevant types for scalp pain are occipital neuralgia (affecting the back of the head) and trigeminal neuralgia (affecting the forehead, temples, or sides of the scalp). Each nerve covers a defined zone, so inflammation along one branch produces tenderness in one predictable area.
A stress-related nerve chemical called substance P also plays a role. Substance P is released by nerve endings under inflammatory stress and is a key driver of localized pain and skin sensitivity. COVID patients with scalp tenderness show elevated substance P activity, and the pattern mirrors what happens in other post-viral pain conditions. The fact that scalp tenderness in COVID patients strongly correlates with loss of smell and taste (66% and 44% overlap, respectively) further supports a neurological origin rather than a purely skin-level problem.
Other Conditions That Can Look Similar
Not every sore spot on the scalp during or after COVID is necessarily caused by the virus itself. A few other conditions can produce similar symptoms, and it’s worth knowing the differences.
- Shingles (herpes zoster): This reactivation of the chickenpox virus can be triggered by the immune disruption COVID causes. Shingles on the scalp typically starts as burning or tingling in one area, followed within days by a cluster of blisters. If you see a rash developing alongside the pain, shingles is more likely than COVID-related nerve inflammation alone.
- Tension-related scalp pain: Prolonged illness, fever, and stress can cause the muscles at the base of the skull and across the temples to tighten, producing sore spots that feel tender to touch. This type of pain tends to worsen with neck movement or pressure and improves with rest.
- Scalp folliculitis or dermatitis: Inflammation of hair follicles from bacterial or fungal causes can flare during illness when immune defenses are redirected. These typically produce visible redness, bumps, or flaking at the tender site.
The distinguishing feature of COVID-related scalp tenderness is that the skin usually looks normal. There’s no rash, no bumps, no visible inflammation. It simply hurts to touch, or even hurts without being touched at all.
What to Expect and How to Manage It
For most people, COVID-related scalp tenderness is temporary. It tends to be most intense during the acute phase of illness and the first few weeks of recovery, then gradually fades. In cases tied to hair shedding, the tenderness may persist for two to three months before both symptoms resolve together. Some long COVID patients report scalp sensitivity lasting longer, particularly those who experienced severe initial infections or who have ongoing neurological symptoms.
Management is largely about reducing inflammation and calming irritated nerves. Over-the-counter anti-inflammatory pain relievers can help during the acute phase. Gentle scalp care matters: avoid tight hairstyles that pull on tender follicles, use mild shampoos without heavy fragrances, and skip heat styling tools while the area is sensitive. Some people find that cool compresses on the sore spot provide temporary relief by reducing local inflammation.
If the tenderness is sharp, electric, or comes in sudden jolts, that pattern is more consistent with nerve pain (neuralgia) than general inflammation. Nerve pain often responds better to medications specifically designed for neuropathic pain than to standard painkillers. If your scalp tenderness persists well beyond your recovery from COVID, or if it’s accompanied by significant hair loss, numbness, or spreading pain, a dermatologist or neurologist can help determine whether the nerve irritation needs targeted treatment or whether another condition has developed alongside the COVID-related symptoms.
