Grim Prognosis: Ashley Olsen's 'Symptoms Have Gotten Worse' In Her Fight With Debilitating Lyme Disease
May 20 2015, Updated 5:22 p.m. ET
Ashley Olsen's struggle with debilitating Lyme disease has taken a turn for the worse.
The petite 28-year-old is suffering from low energy and "she's in a lot of pain," an insider close to the star reveals to In Touch.
As RadarOnline.com reported, Olsen contracted the incurable disease, which is spread through ticks, several years ago.
"Her symptoms have gotten worse," the insider notes. "She's had to take a step back from her business. She used to be in the office all the time, but lately she's often just not well, so she rests a lot at home. She's really having a difficult time."
Unfortunately, Olsen's moods are all over the place as she battles the disease that often causes sufferers pain that feels like pins and needles or burning as well as brain fog and forgetfulness.
"She's really struggling, and it comes out in anger — she's at the point where she's having a hard time dealing," the insider says. "She just seems all-around cranky. Between her pain and her exhaustion," she's really having a difficult time.
