Primary Headache Associated with Sexual Activity
Sex-related headaches can happen before, during, or after orgasm.
The two main types of sex headaches include:
Pre-orgasmic headaches. These develop during sexual activity and involve a dull ache in the neck and back of the head that intensifies as sexual excitement increases.
Orgasmic headaches. These happen suddenly and typically involve sharp, explosive pain at the moment of climax. The pain may linger after orgasm.
These two subtypes, preorgasmic headache and orgasmic headache, were originally included in the International Classification of Headache Disorders, but have since been taken out. Clinical studies were not able to distinguish between these two types, and as a result, medical professionals now just call them “primary headache associated with sexual activity”, regardless of when they occur during or after sex.
Symptoms of Sex Headaches
Common symptoms of sex headache when reaching climax in males include:
Sudden And Severe Pain
The pain may feel intense and throbbing. People sometimes refer to it as a primary “thunderclap” headache. These types of headaches are either getting more intense as sexual excitement builds or they can be sudden and explosive in intensity right before or during orgasm.
One 2021 study, involving 245 people with HSA published found that most participants (85.3%) experienced sudden thunderclap-like onset of headaches.
However, in some people, HSA starts as a mild ache and builds up as sexual activity continues.
Location
You’ll typically feel this type of headache pain at the base of your skull, temples, or behind your eyes. It can also spread across your whole head.
Duration
Once they occur, sex headaches can last from a few minutes to several hours or, in rare cases, even days. Research has shown that up to 40% of primary headaches associated with sexual activity can come and go for over a year.
Associated symptoms
Some men who experience headaches after sex also report symptoms like:
Nausea
Vomiting
Light sensitivity (photophobia)
Sound sensitivity (phonophobia)
In a 2021 case study, researchers detailed the case of a 40-year-old man who was hospitalized who experienced sudden severe headaches after orgasm several times a month. He would also feel nauseated and vomit after.
Why Does My Head Hurt After Sex?
Headaches after sex can happen for several reasons, ranging from harmless and benign to serious. Understanding the cause is key to finding the right treatment.
Primary HSAs are called “primary” because they are not caused by another condition or disorder. These types of headaches are usually harmless, and medical researchers aren’t entirely sure what causes them.
In some cases, sex headaches can mimic other serious medical conditions.
In the previously mentioned study, researchers found that of 245 HSA cases:
15.5% were primary headaches
71% were associated with reversible cerebral vasoconstriction syndrome (RCVS)
2.9% were due to serious causes like:
Subarachnoid hemorrhage
Right internal carotid disease
Moyamoya disease, a rare progressive disorder caused by blocked arteries at the base of the brain
Reversible cerebral vasoconstriction syndrome is a group of conditions involving a narrowing of the blood vessels that supply your brain. It often causes thunderclap headaches.
While the exact cause of reversible cerebral vasoconstriction syndrome isn’t always clear, there’s a link between RCVS and complications like stroke and subarachnoid hemorrhage.
Some of the potential causes of RCVS include:
Pregnancy
Recreational drug use
Certain medications, including antidepressants
Tumors
Some autoimmune conditions (e.g., lupus)
Head trauma
Subarachnoid hemorrhage is a medical emergency involving bleeding in the space between your brain and the surrounding membrane.
This is why people experiencing a new or unexplained headache during sexual activity should see a doctor for evaluation. Imaging of the brain and blood vessels may be needed to rule out the conditions mentioned above, like subarachnoid hemorrhage.
Other Potential Causes of Headaches After Sex
Here are a few other possible reasons you’re getting a headache after orgasm
Benign Exertional Headaches
Sexual activity, like exercise, can increase your blood pressure and heart rate, which can lead to an exertional headache. These types of headaches are typically harmless and happen because of increased blood flow to your brain.
Up to 29% of people with HSA report experiencing benign exercise headaches.
Tension or Stress
Sexual activity can sometimes cause physical or emotional stress. Stress is a common trigger for tension headaches. These headaches often feel like a dull, vice-like pressure on both sides of your head.
Up to 45% of people with HSA report having tension headaches.
Orgasm Migraine
If you have a history of migraine headaches, you might be more likely to experience headaches after sex. Up to a quarter of men with HSA report having migraine attacks.
Sexual activity can sometimes be a trigger for migraine episodes, especially in people who are also:
Dehydrated
Sleep deprived
Stressed
Cluster Headaches
Physical activity, including sexual activity, can trigger cluster headaches. These types of headaches cause intense, one-sided pain, runny nose, and watery eyes.
They’re also most common in men in their 30s or 40s.
Hypertension
Sexual activity naturally raises blood pressure. Men with uncontrolled high blood pressure may likely develop high blood pressure-related headaches.
Medication Side Effects
Headaches are also a potential side effect of some erectile dysfunction (ED) medications such as Viagra (sildenafil).
