Jenna Jameson has Guillain-Barré Syndrome!

Former porn star Jenna Jameson has been diagnosed with Guillain-Barré disease, according to her lover Lior Bitton.

A vomiting Jameson went to the hospital for testing only to be sent home, where she deteriorated further.

She posted a video to Instagram with the caption, "I'm dealing with a little syndrome called Guillain-Barré Syndrome, so I'm working through that."

Jameson addressed rumors that her health crisis could be linked to her vaccination in an Instagram post.

Guillain-Barré Syndrome is a neurological disorder that affects the body's peripheral nerves.

Myelin encases those nerves and protects them from damage.

Myelin acts as an electrical cable's insulation. Insulation on wires prevents electricity from passing through, allowing neurons to conduct at a much faster rate.

As your myelin degrades and your nerves become less efficient at transmitting information, you begin to slow down in the muscles that these nerves supply.

Immune antibodies attack the body in Guillain-Barré syndrome.

Muscle weakness and even paralysis can result from the "person's own immune system damaging the nerves."

Jameson has begun therapy and will remain in the hospital until it is finished, she said.
