Seizures can hurt, but the pain usually comes after the seizure ends rather than during it. Most people who have a generalized tonic-clonic seizure (the kind involving full-body convulsions) lose consciousness and don’t feel anything while it’s happening. The real pain typically arrives in the minutes and hours that follow, as the body deals with the aftermath of extreme involuntary muscle contractions, physical injuries, and intense headaches.
Pain During a Seizure
Whether you feel pain during a seizure depends almost entirely on what type of seizure you’re having and whether you stay conscious through it. In a generalized tonic-clonic seizure, the electrical storm spreads across the whole brain, and consciousness drops out. You’re not aware of what’s happening to your body, so you don’t register pain in the moment.
There are exceptions. Rare cases have been documented where patients retained full consciousness and memory during bilateral tonic-clonic seizures. For these individuals, the seizure activity appeared to stay confined to the brain’s sensorimotor areas while sparing the regions responsible for awareness and memory. Pain was a prominent feature of their experience. But this is uncommon enough that it has been written up in case reports, not studied in large populations.
Focal aware seizures, where you remain fully conscious, are a different story. These can produce genuine pain or uncomfortable sensations depending on where in the brain the seizure starts. Seizures originating in the parietal lobe often cause tingling, numbness, or other sensory disturbances. Seizures that begin in the insula, a deep brain structure involved in body awareness, can trigger feelings of tightness, vibration, nausea, and outright pain. Temporal lobe seizures may bring a rising sensation in the stomach, intense fear, or vertigo. None of these feel good, and some are genuinely painful.
Why Your Body Hurts Afterward
The postictal period, the recovery phase after a seizure, is where most of the pain lives. During a tonic-clonic seizure, every major muscle group contracts violently and simultaneously for 30 seconds to a few minutes. Research comparing the metabolic effects of these seizures to physical exercise found striking similarities to the changes seen in athletic sprinting, but with a key difference: voluntary muscle contractions during exercise are coordinated, while seizure contractions are chaotic and far more intense relative to how briefly they last.
Within seconds, your muscles burn through their immediate energy stores. After about 10 to 20 seconds, they switch to anaerobic energy production, flooding the bloodstream with lactate, the same compound that causes the burn during intense exercise. The result is a level of muscle soreness that can feel like you ran a marathon you never signed up for. Your jaw, shoulders, back, and legs may all ache deeply. This soreness typically peaks in the first 24 hours and gradually fades over one to three days, though it can linger longer after a severe seizure.
Post-Seizure Headaches
Headaches after seizures are extremely common. Studies estimate that 37% to 51% of people experience them, with one large study landing at 43%. These aren’t mild headaches. In that same study, 62.5% of patients with postictal headaches reported pain lasting longer than four hours. Many describe the headache as similar to a migraine, with throbbing pain, sensitivity to light, and nausea. For some people, the postictal headache is actually the worst part of the whole experience.
Physical Injuries From Seizures
A significant portion of seizure-related pain comes from injuries sustained during the event itself. In one study of people with epilepsy, 82.5% had sustained an injury from a seizure at some point. The most common were dental and tongue injuries, affecting nearly 59% of patients. Biting your tongue or the inside of your cheek during the convulsive phase is so common that it’s sometimes used as a diagnostic clue that a seizure occurred.
Other injuries included:
- Head injuries: reported by 61.5% of patients, from hitting the ground or nearby objects during a fall
- Burns: 24%, from falling onto hot surfaces or into hot liquids
- Fractures: 18.3%, including broken arms and, less commonly, compression fractures in the spine from the force of muscle contractions alone
- Shoulder dislocations: about 3%, caused by the extreme pulling forces on the joint during convulsions
Generalized tonic-clonic seizures carried the highest injury risk. In that study, 76% of patients with this seizure type had been injured, compared to lower rates for other seizure types. People who have seizures more frequently also faced a higher overall chance of injury.
Reducing Injury During a Seizure
If you witness someone having a seizure, the most important thing you can do is protect them from their surroundings. Clear away furniture, sharp objects, or anything nearby they could strike. If they’re standing, ease them gently to the ground. Place something soft and flat under their head, like a folded jacket. Remove their glasses and loosen anything tight around their neck.
Once the convulsions stop, roll them gently onto their side with their mouth pointing toward the ground. This keeps the airway clear and prevents choking. Don’t put anything in their mouth, and don’t try to hold them down during the seizure. The goal is simply to let it run its course while keeping the environment as safe as possible.
Chronic Pain and Epilepsy
For people who live with epilepsy and have seizures repeatedly over months or years, pain can become a longer-term issue. CDC data from 2021 to 2022 found that 40.2% of adults with active epilepsy reported chronic pain on most days or every day, compared to 20% of adults without epilepsy. That’s double the rate, making chronic pain one of the most common conditions that coexists with epilepsy.
The reasons for this overlap aren’t fully understood, but repeated seizure-related injuries, ongoing muscle damage, medication side effects, and shared underlying brain mechanisms all likely play a role. Prolonged seizures, particularly status epilepticus (a seizure lasting longer than five minutes or multiple seizures without recovery in between), can cause structural damage to the brain. This damage can, in turn, make the brain more prone to future seizures, creating a cycle that compounds physical wear over time.
For someone experiencing their first seizure, the soreness and headache will almost certainly resolve within a few days. But for those living with recurrent seizures, managing pain becomes an ongoing part of living with the condition, not just a one-time recovery.
