Jenna Jameson Reveals Doctors Still Haven't Found Cause of Mystery Illness

Jenna Jameson has revealed that doctors still haven't discovered the cause of her mystery illness, two months after she went into hospital.

The former adult film star, 47, announced back in January that she had been diagnosed Guillain-Barré syndrome. Her partner, Lior Bitton, revealed days later that she had been misdiagnosed with the rare autoimmune disorder.

In a new health update, shared on her Instagram account on Thursday, Jameson said that she remains unable to stand as she recuperates at home following several weeks in a Hawaii hospital.

"I wanted to pop on and say hello. It's been a minute since I've been on," the model said in the self-shot video. "I'm still sick. As you can still see, I'm in bed. But I'm at home, which is really nice. I've been getting a lot of sleep.

"We l don't know exactly what's going on. I still am unable to stand, but I am feeling better, and things are going a lot better, so thanks for your support."

In February, Jameson posted a video in which she showed the toll that the ongoing illness has taken on her legs as she continues to rely on the use of a wheelchair.

"I am just resting, obviously. I still have more testing to do," she said. "But it seems there's something off with my femoral nerve and it's affecting my strength in my legs, so I am still in a wheelchair, unfortunately. But I hope to be out of the wheelchair soon and walking."

Jameson then angled the camera down to one of her legs, as she added: "So, you can see I still have movement in my leg, but my quad strength is really, really, really weak, and as you can see, I have some atrophy happening.

"My legs are incredibly skinny. But don't get too alarmed because my legs have always been ultra skinny. So don't judge me. We will be back to the best soon."

Back in January, Jameson's partner Bitton explained in a post on the star's Instagram account that she had been "throwing up for a couple weeks," prompting her initial hospitalization. She was sent home after undergoing a CT scan, per Bitton.

"Then she came back home and she couldn't carry herself," Bitton said. "Her muscles in her legs were very weak. So she wasn't able to walk to the bathroom.

"She was falling on the way back or to the bathroom. I would have to pick her up and carry her to bed. And then within two days it got really not so good. Her legs started to not hold her—she wasn't able to walk."

When Jameson was initially diagnosed with Guillain-Barré, some of her Instagram followers enquired whether it had been caused by taking a COVID vaccine. The disorder has been reported to be a "very rare" possible side-effect of the Johnson & Johnson COVID shot.

"I did NOT get the jab or any jab," Jameson said in an Instagram post that has since been deleted. "This is NOT a reaction to the jab. Thank you for your concern."

According to the Centers for Disease Control and Prevention (CDC), COVID-19 vaccines are "safe and effective." The CDC recommends that those seeking vaccination "get either Pfizer-BioNTech or Moderna (mRNA COVID-19 vaccines). The mRNA vaccines are preferred over Johnson & Johnson's Janssen COVID-19 vaccine in most circumstances."

The health agency describes Guillain-Barré as a "rare autoimmune disorder in which a person's own immune system damages the nerves, causing muscle weakness and sometimes paralysis."

With symptoms of the potentially deadly disorder lasting anything from weeks to several years, some patients are left with permanent nerve damage. A large number of those diagnosed with Guillain-Barré go on to make full recoveries.
