The pain lasts for several minutes, or maybe it lingers for a couple of hours. What you may have experienced is known as an orgasm headache, a rare — but often harmless — type of sex headache that happens before or at the moment of sexual release. An orgasm headache is one of two types of sex headaches. The second type is a sexual benign headache. Sexual benign headaches start as a dull pain in the head and neck that builds up as you become more sexually aroused, leading to a painful headache.
Sex headaches are brought on by sexual activity — especially an orgasm. You may notice a dull ache in your head and neck that builds up as sexual excitement increases. Or, more commonly, you may experience a sudden, severe headache just before or during orgasm. Most sex headaches are nothing to worry about. But some can be a sign of something serious, such as problems with the blood vessels that feed your brain. Most sex headaches last at least several minutes.
Primary headache associated with sexual activity (Orgasmic and Pre-orgasmic Headache)
An orgasm headache is intense and it starts suddenly, just before or during an orgasm. These headaches are usually harmless, and a person can often treat them with over-the-counter pain medications. However, headaches during sex can sometimes signal a more serious condition.
Primary headache associated with sexual activity, previously known as orgasmic or pre-orgasmic headache, is a rare headache type brought on by or occurring only during or after sexual activity. People with new or never-evaluated headache associated with sexual activity should be carefully assessed by their doctor for an underlying cause and considered for imaging of their brain and the blood vessels in their head to exclude conditions like subarachnoid hemorrhage, arterial dissection and reversible cerebral vasoconstriction syndrome. Primary headache associated with sexual activity is commonly described as bilateral on both sides of head and often located occipitally back of the head. Primary headache associated with sexual activity generally lasts from 1 minute to 24 hours with severe pain and up to 72 hours with mild pain. It may have similar features to migraine and must be distinguished from migraine triggered by sexual activity.
