This Is Why Your Lower Back Hurts During Your Period

The Question: I have my period and my back hurts. Why? Also, ow.

We’re just going to say it: periods aren’t fun.

It’s understandable if you just want to crawl into bed and never come out during that time of the month. Especially when body aches — particularly the lower back pain — kick in.

And, really, what’s the deal with that? Why is your back throbbing when your uterus is the one doing all the work?

Let’s break it down.

First of all, nothing’s wrong with you. Lower back pain during your period is totally common. It’s caused by contractions in the uterus, which radiate through the web of nerves within your pelvic region. As your body contracts to rid itself of the uterine lining, it can sometimes press on blood vessels in the area, limiting or cutting off the supply of oxygen to the nearby muscles.

“Many women get back pain during their periods,” Dr. Houman Danesh, director of integrative pain management at Mount Sinai Hospital in New York City, told The Huffington Post. “This pain is from the uterus contracting to shed the lining which has built up since the last cycle… The phenomenon is described as ‘referred pain.'”

“Referred pain” is pain felt in a part of the body other than its actual source. If you’re just about to get your period, your uterus might be contracting in preparation for the upcoming activity. This is totally common and normal, and the pain can affect your thighs as well as your lower back.

fibroids in the uterus, pelvic inflammatory disease, or an infection.
