Yes, headache is one of the most common symptoms of COVID-19. Nearly half of people with COVID experience a headache during the acute phase of infection, and it often shows up early, sometimes before cough, fever, or other recognizable symptoms. If you have a new, unusual headache and you’re wondering whether COVID could be the cause, it’s a reasonable suspicion.
How Common Headaches Are With COVID
About 47% of COVID patients report a headache during the acute phase of illness. That makes it one of the top symptoms alongside fever, cough, and fatigue. In roughly 39% to 55% of cases, the headache begins on the very first day of illness. For 6% to 29% of patients, headache is the first symptom to appear, sometimes days before anything else develops.
In some documented cases, a severe headache preceded respiratory symptoms like cough by up to a full week. That gap can make it easy to dismiss the headache as unrelated, especially if you don’t yet have the “classic” signs of a respiratory infection.
What a COVID Headache Feels Like
COVID headaches tend to be moderate to severe and are often described as throbbing. They frequently affect both sides of the head, particularly the temples and forehead. Many people also report sensitivity to light, noise, and sometimes smell or touch, which makes these headaches feel similar to migraines.
One of the distinguishing features is how poorly they respond to medication. People who have a history of migraines often say their COVID headache mimics a typical migraine attack but doesn’t improve with the treatments that normally work for them. Others describe a headache that feels entirely different from anything they’ve experienced before, either more intense, longer lasting, or both. In documented cases, the headache persisted for several days straight, with standard pain relievers having little effect on intensity.
Headache Patterns Across Variants
The likelihood of getting a headache with COVID has shifted as the virus has evolved. The Delta variant produced headaches in an estimated 33% to 62% of infections, significantly higher than the original strain (about 21%) or Alpha variant. With Omicron and its subvariants, which are currently dominant, headaches remain very common. They rank as the second most frequent symptom after upper respiratory issues like sore throat and congestion, though the overall rate appears slightly lower than during the Delta wave.
The practical takeaway: headache has been a prominent COVID symptom across every major variant, and that remains true today.
Why COVID Causes Head Pain
COVID headaches aren’t simply a side effect of fever or dehydration. The virus triggers head pain through multiple pathways. SARS-CoV-2 can bind to receptors found throughout the nervous system, potentially irritating pain-sensing nerve networks in and around the brain directly. At the same time, the immune system’s inflammatory response to infection floods the body with signaling molecules that amplify pain sensitivity and cause blood vessels to swell. This combination of direct nerve irritation and widespread inflammation creates a headache that can be unusually stubborn and intense compared to what you’d expect from a typical cold or flu.
COVID Headache vs. Migraine or Tension Headache
Telling a COVID headache apart from an ordinary headache isn’t always straightforward, but a few patterns help. Tension headaches typically produce a dull, band-like pressure around the head without light sensitivity or nausea. COVID headaches are more likely to throb, cause sensitivity to light and sound, and feel significantly more severe.
Migraine sufferers face a trickier distinction, since COVID headaches frequently mimic migraine characteristics. The key clues are context and treatment response. If your headache came on suddenly, feels different from your usual pattern, and doesn’t respond to your go-to migraine medication, COVID is worth considering, especially if you’ve been exposed recently or have even mild accompanying symptoms like a scratchy throat, fatigue, or body aches. A rapid test can clarify things quickly.
Managing a COVID Headache
The CDC recommends treating mild COVID symptoms at home with over-the-counter pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin). These can take the edge off a COVID headache, though they may not eliminate it entirely. Staying well hydrated, resting in a dark and quiet room, and applying a cold compress to your forehead or temples can also help.
If your headache is severe enough that you can’t function, persists for more than a few days without improvement, or comes with neurological symptoms like confusion, difficulty speaking, sudden vision changes, weakness on one side of your body, or a stiff neck, those warrant urgent medical attention. These could signal complications beyond a straightforward infection-related headache.
Headaches That Linger After COVID
For some people, the headache doesn’t stop when the infection clears. Persistent headache is one of the more common features of long COVID. In one study tracking patients over time, 50% still reported headaches 12 to 15 months after their initial infection. Even at the 15-month mark, about 41% of those who developed headaches during acute COVID still had them.
These long-lasting headaches often resemble chronic migraines, with throbbing pain, light sensitivity, and episodes that come and go over weeks or months. People with a prior history of headache disorders appear more likely to develop persistent post-COVID headaches, but they also occur in people who never had significant headaches before getting sick. If a new headache pattern develops after a confirmed COVID infection and doesn’t resolve within a few weeks, a headache specialist can help evaluate treatment options specific to post-COVID headache.
