Yes, a migraine is a legitimate reason to call in sick. Migraine is a neurological condition, not just a bad headache, and the symptoms it produces can make safe, productive work impossible for hours or even an entire day. If you’re dealing with an active migraine attack, staying home isn’t an overreaction.
Why Migraines Make Work Unsafe or Unproductive
A migraine attack involves far more than head pain. It can cause intense sensitivity to light, sound, and smell, along with nausea, visual disturbances, and difficulty thinking clearly. In a typical office with fluorescent lighting, screen glare, and ambient noise, these symptoms don’t just cause discomfort. They actively prevent you from doing your job. For people in roles that require driving, operating equipment, or making quick decisions, working through a migraine can be genuinely dangerous.
The American Migraine Foundation describes migraine as a debilitating neurological disease that affects roughly 40 million people in the U.S. The working-age population is hit hardest: CDC data from 2021 shows that 7.4% of women and 2.5% of men between ages 18 and 44 reported being significantly bothered by migraine or severe headache in the prior three months. This is not a rare or trivial condition, and you are far from the only person in your workplace dealing with it.
The Full Timeline of a Migraine Attack
One reason people underestimate migraines is that they think of them as lasting a few hours. In reality, a migraine attack can unfold across four phases: a warning phase (prodrome), aura, the headache itself, and a recovery phase (postdrome). The headache alone can last anywhere from 4 to 72 hours. But even after the pain ends, the attack isn’t over.
The postdrome, sometimes called a “migraine hangover,” affects most people who get migraines. A study published in Neurology found that the most common postdrome symptoms were fatigue (feeling tired or weary), difficulty concentrating (reported in 56% of attacks), and neck stiffness (42%). In about half of migraine attacks, the postdrome resolved within six hours after the pain stopped. But in 93% of cases, it took up to 24 hours to feel fully normal again. That means even if your headache clears by noon, you may still be cognitively foggy and exhausted well into the evening or the next morning.
This recovery window matters when you’re deciding whether to push through. Showing up while you can barely concentrate doesn’t help your employer, and it often prolongs your recovery.
How to Know If Your Migraine Is “Bad Enough”
There’s no objective threshold you have to meet before you’re allowed to call in sick. But if you want a framework, neurologists use something called the Migraine Disability Assessment (MIDAS), which scores how many days over the past three months you’ve lost to migraine across work, household chores, and social activities. A score of 11 to 20 indicates moderate disability; 21 or higher indicates severe disability. Even a score of 6 is enough that the National Headache Foundation recommends discussing it with your doctor.
In practical terms, if your migraine is causing any of the following, working through it is unlikely to go well:
- Light sensitivity that makes screens or overhead lighting painful
- Nausea that worsens with movement or concentration
- Visual disturbances like blind spots, zigzag lines, or blurred vision
- Cognitive fog that makes reading, writing, or decision-making difficult
- Pain severe enough that you can’t focus on a conversation
You don’t need all of these to justify staying home. Any one of them can make a workday pointless or harmful to your recovery.
You Don’t Owe a Detailed Explanation
When calling in, you can simply say you’re sick. You’re not required to specify that it’s a migraine, and doing so sometimes invites skepticism from people who think “headache” and “migraine” are the same thing. If your workplace asks for more detail, “neurological symptoms” or “a migraine attack” is sufficient. Most company sick leave policies don’t distinguish between types of illness.
If migraines cause you to miss work repeatedly, it’s worth knowing that migraine can qualify as a disability under the Americans with Disabilities Act. The ADA doesn’t list specific conditions. Instead, it protects anyone with an impairment that substantially limits a major life activity. The Equal Employment Opportunity Commission has recognized migraine as an impairment, which means if your migraines significantly affect your ability to work, concentrate, or function, you may be entitled to reasonable accommodations. These could include flexible scheduling, the ability to work from a dimmer space, or permission to work from home during an attack.
Recurring Migraines and Long-Term Planning
If you’re searching this question, there’s a good chance this isn’t your first migraine and it won’t be your last. People who lose multiple workdays per month to migraine often benefit from preventive treatment, which can reduce both the frequency and severity of attacks. Tracking your migraine days, triggers, and symptoms gives your doctor the information they need to recommend the right approach.
Having a plan with your manager before an attack hits also reduces stress on both sides. Some people establish a protocol: a short text or message in the morning, with the understanding that they’ll be back when the attack passes. This kind of arrangement is far easier to set up during a healthy week than in the middle of an attack when you can barely look at your phone.
Taking a sick day for a migraine isn’t a sign of weakness or an excuse. It’s a rational response to a neurological event that temporarily impairs your ability to function. Resting during an attack helps it resolve faster, while pushing through often extends the cycle of pain, postdrome symptoms, and reduced performance across multiple days instead of one.
