Endometriosis, if you're unfamiliar, is when tissue similar to your uterine lining is found in other parts of your body outside your uterus. The condition affects millions of women worldwide and can be debilitating: Many women struggle with extreme pelvic pain and heavy periods, and in some cases, they can become infertile.

Several celebrities have opened up about living with endometriosis, with the most recent being Padma Lakshmi, who talked about her endo-induced migraine.

Padma Lakshmi shared a selfie holding her arm up to her head, and talked about her endometriosis-induced migraine.

"Day three of endo-induced migraine from clenching my teeth due to cramps," she stated. "Even my ear hurts."

This isn't the first time Lakshmi opened up about having endometriosis: She co-founded the Endometriosis Foundation of America, after all. However, the actress' Instagram post is raw, real, and a reminder that the side-effects of the condition present themselves in a myriad of ways.

Tia Mowry has also talked about having endometriosis, detailing how it changed her diet.

In her book "Whole New You," Mowry revealed how she changed her diet and her philosophy around food to help with her endo-induced symptoms.

After a doctor recommended clearing up her diet, Mowry cut processed meat, dairy, packaged snacks, and refined sugar. She found that her pain was reduced since being diagnosed in 2006.

Halsey also came clean about finding out she had a disease that took way too long to diagnose.

The singer opened up about feeling like a "prisoner in her own body," explaining how doctors told her that she was just dealing with bad period cramps, and even misdiagnosed the star with PCOS.

However, she didn't let any of that talk get her down.

"I have managed to live a wild, incredible and unpredictable life with Endo, and I'm here for you,"  she told her fans.

Julianne Hough thought that endo was just her period.

Hough was diagnosed in 2008 and was one of the first celebrities to open up about endometriosis.

"For the longest time, I thought: This is the way my period is," Hough told Glamour. "I didn't want to complain, so I'd just deal with it and ignore it."

The actress revealed she had a "half-assed diagnosis" and "half-hearted treatments" when she was first diagnosed with endometriosis.

“When all you know is pain, you don’t know that that is not normal.  It is not a woman’s lot to suffer, even if we’ve been raised that way,” she revealed in 2011.

Lena Dunham has been extremely vocal about her endometriosis diagnosis.

In a powerful Lenny Letter, Dunham talked about how she eventually had to have laparoscopic surgery to definitely diagnose her endometriosis. She revealed she was having monthly injections to stop her production of estrogen, which helped some.

"I am strong because of what I've dealt with," she said. "I am oddly fearless for a wimp with no upper-body strength. And I am no longer scared of my body. In fact, I listen to it when it speaks. I have no choice but to respect what it tells me, to respect the strength of its voice and the truth of my own."

Daisy Ridley got real about how endometriosis does a number on her skin.

Ridley was diagnosed when she was 15, and while her pain subsided after many consultations and a laparoscopy, she felt the pain return after eight years. However, what took the biggest toll on her confidence was her skin.

“I’ve tried everything: products, antibiotics, more products, more antibiotics, and all that did was leave my body in a bit of a mess."

Only after cutting dairy and reducing her sugar intake did she begin to see results.

Remember: You're not alone in your endometriosis diagnosis.
