Jameson took to Instagram to confirm a medical diagnosis that has her in some pain...Guillain-Barré Syndrome! This condition is a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system. Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body!

It's a relatively mild condition that is usually treatable, but can be known to cause bigger nerve problems with age. Over the weekend, her partner, Lior Bitton, posted a video on her account explaining that she was undergoing testing after throwing up a great deal for several weeks.

A trip to the hospital and a CT scan didn't reveal anything and she was sent home, he said. But, according to Bitton, her conditioned worsened. "Then she came back home and she couldn't carry herself - Her muscles in her legs were very weak, so she wasn't able to walk to the bathroom."

The news had many fans speculating if these symptoms were caused by the COVID-19 vaccine, with Jameson having been a supporter of natural immunity in the past. But Jameson herself was quick to shut down any rumors that her current condition had anything to do with vaccination. "PS I did NOT get the jab or any jab," she wrote in the caption of the video. "This is NOT a reaction to the jab. Thank you for your concern."

The coming weeks will tell us more about the severity of her condition, but she seems to be in good spirits, and fans have already sent her good wishes in the thousands of comments. Let's hope she gets well soon.
