@abopp2022 I had plummeting platelet counts for no apparent reason — they call that "Immune thrombocytopenic purpura (ITP)", but it turned out to be from cirrhosis. I had recently diagnosed (within a few years) diabetes, shaky hands, which were diagnosed as "essential tremor", excruciating cramps in my thighs, trouble sleeping, causing fatigue during the day, I was always cold, and I had fluid retention in my feet (edema), but that was not constant. It was primarily when I traveled probably because when you are eating out a lot you tend to eat more sodium, which I use very little of at home.
The thing that finally brought all of this to a head was episodes of confusion, called hepatic encephalopathy (HE). That was what made the doctors know there was something wrong but even then it took a year a half to figure it out, and it was the neurologist who finally suggested it was a liver problem. Because of the confusion, it was assumed it was a neurological problem.
The only problem I had in common with yours was the sleeping problem leading to daytime fatigue.
