In anticipation of possible pregnancy, a woman's body releases an egg from her ovaries (called ovulation) and the lining of her uterus thickens to form a welcoming environment to that egg to nest should it be fertilized. If fertilization doesn't occur, a woman then menstruates, or has her period.
A woman's body goes through that process, called a menstrual cycle, once every 21 to 35 days. And a period can last 2 to 7 days.
Because the uterus is contracting to shed the built-up lining and blood, women often experience cramps during their period, especially on the first day or two. Pain in the back or legs is also common.
Experiencing severe and frequent pain during periods is a menstrual condition called dysmenorrhea. There are two types of dysmenorrhea:
Primary dysmenorrhea. Caused by severe and abnormal uterine contractions, women with this condition experience pain early on, with their first period and continue to have severe pain with every menstrual cycle throughout their lifetime.
Secondary dysmenorrhea. This is the result of a physical cause (pelvic inflammation, endometriosis or another disease or condition) and is not something a woman experienced with every period early in life.
Although the pain caused by uterine contractions is often centered in a woman's abdomen, the pain can radiate to her back and/or down her legs.
Any woman may experience pain in her legs during her period, however, that is one of the common signs of dysmenorrhea.
There are several home remedies that can reduce pain in the legs during your period. Your doctor can tailor a treatment plan that just right for you which may include over-the-counter pain medication.
