Crystal (Harris) Hefner, wife of Playboy founder Hugh Hefner, revealed on Sunday that she's been diagnosed with Lyme disease.
The 29-year-old model shared the news in a cautionary message posted to Instagram, warning followers to get tested for the illness if they "have EVER GONE HIKING" because it is spread by deer ticks, which are often found in the wilderness.
"I was diagnosed a few days ago and have a long road ahead of me," Crystal wrote, adding that she doesn't even remember getting bit by a tick at any point. "The symptoms are vast and when it has been left untreated for a long time can turn into MS, Alzheimer's, Parkinson's, Dementia and ALS."
If you have EVER GONE HIKING, please get tested for #LymeDisease. The best lab to do this is called "Igenex" they are based out of Palo Alto. I was diagnosed a few days ago and have a long road ahead of me. Supposedly you get it from ticks but I have absolutely no recollection of being bit or having a rash or ANYTHING. Most importantly there are SO MANY of you carrying Lyme that don't even know you have it. Probably because the ticks can be the size of specs. I always thought of ticks to be big and noticeable. The symptoms are vast and when it has been left untreated for a long time can turn into MS, Alzheimer's, Parkinson's, Dementia and ALS. Symptoms can range from sore muscles, sore back, sore neck, anxiety, fatigue, heart palpitations, muscle twitches, bladder pain, vision or hearing problems, swollen lymph nodes, flu like symptoms, brain fog, memory problems. Having just one of these could mean you have Lyme. Please please get tested. It is a disease so many people are living with and is becoming an epidemic. I always thought I was a hypochondriac. Doctors told me it was just "stress" or "all in my head" but I finally figured it out and you can too. Lyme is also related to syphilis and can be sexually transmitted and also passed from mother to child during pregnancy. #LymeDisease #lymewarrior 💚 please tag some friends to raise awareness for this illness not many people know about 💚
"It is a disease so many people are living with and is becoming an epidemic," she continued, after detailing Lyme disease's many symptoms. "I always thought I was a hypochondriac. Doctors told me it was just 'stress' or 'all in my head' but I finally figured it out and you can too."
The day before Crystal shared the news and the dire warning, she seemed much happier. She posted a sexy bikini selfie to Instagram that showed off her flawless figure, in which she looked like the picture of perfect health.
The Playboy playmate is among a number of celebrities battling Lyme disease. Real Housewives of Beverly Hills star Yolanda Hadid has long been battling the crippling illness, which two of her children, Bella and Anwar Hadid, also suffer from, as does singer Avril Lavigne.
