Is my nervous system attacking my body?

I’m reaching out because I’d love to hear if anyone else has dealt with something similar to this.

Basically, a friend of mine spent several hours on a flight about two years ago, and because her head wasn't positioned right, she ended up with some serious neck issues.
After six months of various therapies, she decided to try chiropractic adjustments. She stuck with those treatments for a full six months. Since then, things have taken a weird turn, so she went in for some testing. To make a long story short, her blood work is a mess, her organs are starting to fail, and the diagnosis is that her nervous system is essentially attacking her body. Her current treatment has to be very mild because her liver can't handle stronger medications, and she isn't seeing any progress at all.

If anyone here has heard of anything like this before, or if you know of any herbal remedies or natural supplements that might help, please let me know...
Because modern medicine just doesn't have 😢

Thanks!

What’s her actual diagnosis? What meds is she on? This explanation is all over the place and honestly pretty confusing. I doubt anyone can actually give a helpful answer like this. 🙂
