One of this year's most anticipated new movies is the remake of A Star Is Born starring Bradley Cooper and Lady Gaga.
The pop star graced the October cover of Vogue to promote the film, and in a new tell-all interview she discussed plenty of hard topics.
One of the most revealing exchanges in the new profile of the pop star focused on her fibromyalgia - a chronic condition that causes excruciating joint and nerve pain.
And the pop star says we all need to learn a thing or two about the disease.
"It's really a cyclone of anxiety, depression, PTSD, trauma, and panic disorder."
The cause of fibromyalgia is still not very well understood, but it is often associated with traumatic events.
Gaga believes her case was "triggered" in her teenage years, and has been getting progressively worse because of the stresses of her career.
"For me, and I think for many others, it's really a cyclone of anxiety, depression, PTSD, trauma, and panic disorder, all of which sends the nervous system into overdrive, and then you have nerve pain as a result."
Experts agree with the "Born This Way" singer: a study in the Journal of the International Association for the Study of Pain found that post-traumatic stress disorder can be a risk factor for fibromyalgia.
While doctors once thought the condition was "all in a patient's head," they now agree that fibromyalgia pain is very, very real.
"For me, with my mental-health issues, half of the battle in the beginning was, I felt like I was lying to the world because I was feeling so much pain but nobody knew," Gaga explained.
"So that's why I came out and said that I have PTSD, because I don't want to hide - any more than I already have to."
"People need to be more compassionate. Chronic pain is no joke."
Despite her fame, Gaga says that she struggles to be believed about her condition like any other patient with an "invisble illness."
"I get so irritated with people who don't believe fibromyalgia is real," she said.
"People need to be more compassionate. Chronic pain is no joke. And it's every day waking up not knowing how you're going to feel."
The singer has cancelled several tour dates through the years to manage her nerve pain or heal a lingering hip injury.
But each time, she struggled to convey how painful and nerve-wracking her condition really is.
"You know that feeling when you're on a roller coaster and you're just about to go down the really steep slope?" she asked.
"That fear and the drop in your stomach? My diaphragm seizes up. Then I have a hard time breathing, and my whole body goes into a spasm."
"[Trauma and pain] are keeping me from living a normal life."
Last year, Gaga posted a dramatic message to fans on Instagram after canceling a series of tour dates on her doctor's orders.
"I have always been honest about my physical and mental health struggles," she wrote.

I have always been honest about my physical and mental health struggles. Searching for years to get to the bottom of them. It is complicated and difficult to explain, and we are trying to figure it out. As I get stronger and when I feel ready, I will tell my story in more depth, and plan to take this on strongly so I can not only raise awareness, but expand research for others who suffer as I do, so I can help make a difference. I use the word "suffer" not for pity, or attention, and have been disappointed to see people online suggest that I'm being dramatic, making this up, or playing the victim to get out of touring. If you knew me, you would know this couldn't be further from the truth. I'm a fighter. I use the word suffer not only because trauma and chronic pain have changed my life, but because they are keeping me from living a normal life. They are also keeping me from what I love the most in the world: performing for my fans. I am looking forward to touring again soon, but I have to be with my doctors right now so I can be strong and perform for you all for the next 60 years or more. I love you so much.

The singer revealed that she was suffering "not only because trauma and chronic pain have changed my life, but because they are keeping me from living a normal life."
But thankfully, Gaga says that with the help of her team of doctors she is "getting better every day."
There is currently no cure for fibromyalgia, but many patients manage their symptoms with pain relieving medicine and antidepressants.
