Actress Tatum O’Neal is getting candid about living with rheumatoid arthritis, sharing a photo of her bruised and scarred back to social media followers.

The actress wrote in December that she was seeking treatment for the condition and has been open with fans about her health journey in the past. In her post on Wednesday, she gave followers a look at the strain that the treatment has taken on her body.

“Living with rheumatoid arthritis. A fall scratch scar on my right hip. And the back surgery scar from eight years ago,” she captioned the graphic post. “My last back surgery scar is on the front from February.”
