This has been going round for years about this illness, this theory. Thank you for posting JF though.
I wish there was a damn cure though whatever causes it. Living life with fibromyalgia in my case bought on by PTSD has whole of life his horrendous. Trekker will vouch for that.
Chronically debilitating, exhausting and painful is as much as I can do to sum it up. There are no words. I know many of you and you JF will get that from your own health conditions
