Headaches attributed to substance withdrawl are usually diagnosed only when the headache resolves or dramatically reduces in pain within seven days after the user no longer exposes themselves to the substance. Withdrawal headaches are usually bilateral (both sides of head), occurring when an interruption in the daily intake of a substance is delayed, stopped or interrupted. The more common withdrawal headaches occur with caffeine, oestrogen and opioids.
The caffeine headache is caused by dilation of blood vessels occurring multiple days after consumption of large quantities of caffeine. For extreme cases, complete termination of caffeine consumption is proposed, though for most incidents, it is recommended to avoid excessive intake of caffeine. The caffeine headache is bilateral and pulsating or throbbing in nature. For migraine sufferers, caffeine withdrawal may trigger a migraine headache. A caffeine withdrawal headache will be relieved within 1 hour by a moderate amount of caffeine, though the headache will be gone within 7 days after total caffeine withdrawal.
Oestrogen is a steroidal sex hormone produced mainly in the ovaries but possible also in the adrenal gland and placenta. It is responsible for female sexual development, such as breasts, hair distribution and development of the genitals and womb. During the menstrual cycle is acts on the female genitalia to produce the environment suitable for fertilization, implantation and nutrition of the early embryo. Oestrogen and compounds including oestrogen are sometimes taken by women who have undergone a hysterectomy, for relief from menopause discomfort or for contraceptive purposes. If oestrogen is taken in daily for more than 3 weeks, a headache or migraine headache may develop within 5 days after the last use of oestrogen. Such headaches occur, for example, during the pill-free period of oral contraceptives or after a term of supplementary oestrogen. This headache will usually resolve itself within 3 days.
Read an excellent summary about opioids and opioid abuse here. The opioid withdrawal headache is of a pulsating quality, bilateral (both sides of head) in nature. The headache will arise within 24 hours after the last opioid intake, and will resolve itself within 7 days. Depending upon the severity of opioid dependency, withdrawal may include a multitude of other symptoms; in severe cases, medical attention may be necessary.
