Hormonal headaches are a very painful and seriously debilitating ailment that affects only women.

Fluctuations in estrogen and progesterone are known to be behind hormonal headaches in women.
Hormonal headaches are a part of the overall premenstrual cycle, and can start as early as eleven days before the menstrual cycle. Symptoms of hormonal headaches typically involve fairly serious pain not unlike a migraine, usually accompanied by a sensitivity to light and loud noises. The pain is usually described as a throbbing sensation.

A large percentage of women will eventually experience a hormonal headache.
The occurence of hormonal headaches is difficult to predict, although contraceptives are known to have an effect on their frequency. In some women, oral contraceptives can actually increase the occurence of hormonal headaches, while in others it ends up reducing the frequency of the headaches.

Accurately predicting the outcome of oral contraceptive use is difficult. Outside of contraceptives, the the real reasons behind hormonal headache remain unknown. Preventing hormonal headaches can be difficult, or at least hard to do.

Fortunately, treatment for hormonal headaches can potentially be far more effective.
Over the counter non-steroidal anti-inflammatory drugs can do a good job of handling the symptoms of hormonal headaches. Treatment with these over the counter drugs around five to seven days prior to a menstrual period can mitigate their effects.
Aspirin, ibuprofen, and acetaminophen are all effective treatments for hormone headaches. These NSAID medications can possibly also play a role in reducing other premenstrual symptoms.

Migraine medications, such as triptans, can also be used to lessen the impact of hormone headaches.
Although not a direct treatment for the cause of the headaches, triptans can significantly reduce the associated pain. Triptans and NSAID medication should see use on a limited basis, because they can cause reactions if overused. Overuse of both triptans and NSAID medication can cause "rebound" headaches in which the symptoms present even stronger.

In addition to the premenstrual cycle, hormonal headaches can be triggered during other periods of wide fluctuation in hormone levels.
The early periods of childbirth can cause widespread changes in hormone levels, and this can commonly result in hormonal headaches. The days after childbirth are also a prime time for hormonal headaches to occur. Menopause can also frequently be associated with hormonal headaches.
