Sex Headaches

In rare instances, headaches can be brought on by sexual activity — especially with orgasm. You may notice a dull ache in the 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 the brain.
