Global pop star Selena Gomez has opened up about developing arthritis as a consequence of lupus. The singer, who has long been candid about her health challenges, was first diagnosed with lupus in 2013 and later underwent a kidney transplant. In a recent conversation with Amy Poehler on her podcast ‘Good Hang with Amy Poehler,’ Gomez discussed her Rare Beauty brand, including its easy-to-use packaging, and shared how her personal health experiences influenced these choices. “I have arthritis in my fingers because of my lupus,” she said. “Before I started the right treatment, even simple things like opening a water bottle were really painful.”What Is Lupus?Lupus is an autoimmune condition that causes inflammation throughout the body.
