I know two people with it. And it's been debilitating for them. I know one person who had it but has mostly gotten over it after about 2 years, so there IS hope for some.

Not to dump a bucket of ice water in this, but the arthritis I live with now, most likely started with a virus I caught in 1987. I had symptoms very like LC for a few years in the 80s/90s, then moderate remission, then slow degrading until it jumped up hard in the 2010s. We just...don't know.
