Menstrual cramps are one of the most common side effects of vasocongestion in adult females. Although pain and discomfort varies among individuals, vasocongestion is an essential part of the shedding of the lining of the uterus. Abnormal vasocongestion during the menstrual cycle can lead to irregular bleeding, severe and debilitating cramps and anemia caused by increased menstrual flow.
The temporary vasocongestion of the cheeks of the face is called blushing. It may be caused by the emotions of anger or embarrassment. The illness of rosacea is a chronic vasocongestion condition of the face that primarily affects the cheeks and nose, but may include other areas such as the eyes and chin.
Human sexual behavior
Vasocongestion is essential for sexual procreation in mammals since this is the force that causes the hardening of a penis during an erection. The same force in woman leads to the hardening of the clitoris and vaginal lubrication during sexual arousal. The decrease in vasocongestion in post-menopausal women may require some women to use artificial sexual lubricant to avoid pain during sexual intercourse. 
Unpleasant side effects of sex-related vasocongestion may lead to the cramp-like pain of "blue balls" in males and an unpleasant pelvic "heaviness" in women, similar to the start of the menstruation cycle.
