It will probably show up eventually. It was emailed from a link in an email to me, I think.
At any rate, it was the middle part of the story. Probably significant. After decades of debility, I stumbled on to answer that my GP thinks is it. It was B6 deficiency that now yields excellently to 1800 mg daily, split doses. Though even at a crisis in at 10/2011, the B6 serum tests showed normal. But metanephrines were not even measurable, probably due to inability to convert enough stuff to make necessary neurochemicals. Hypothalamic signs (i.e., hypothermia
below 67 and hyper above 78, gasping with yawns, etc.) were prominent. Temperature generally around 97 or less.
The B6 supplements have ended the faitgue, malaise, brain fog, etc., that used to hallmark everyday. My appetite returned, gone for decades. My temperature has returned to normal. My hair has stopped falling and eyelashesd are regrowing. Surprisingly, muscles are regenerating and gaining mass while I am losing fat. Perhaps like returned POW, except for the fat which I retained because I always had enough calories.
The sole change in my regimen, except for the increased ADLs that I can now perform, is the addition of the B6. First to 600, then, 1400, then 1800, while finding best dose. That and the almost ravenous consumption of about 70 to 80 pounds of sirloin beef, grilled very rare, which developed an overwhelming craving for. I assume my body was wanting the amino acids. But the muscle recovery is stunning. Nearly like in my teens and twenties, if you can believe that.
Anyway, my condition was extreme and longlived, and I needed to convey the degree top which it had effected me. Nearly every other complaint I had including carpal tuinnel, numb feet, Reynaud's signs, etc. have vanished. My main concern about the tongue is that it might herald something apart from the B6 dependency.
I am a male Caucasian (something info in the lost email) who is an Atlantic Modal Haplotype genetically, mainly from the British Isles.
Unless there is other info you need, this should allow you to figure what may have happened to the tongue during those years if caused by B6 dependency.
Your point about melanin was well taken. I am educated enough to understand this biology, so toss it at me if you wish. But as you note, it is melanin (though the buds are purplish black, miostly) that causes it. My question would be what physical process, for what reason, deposited there.
I will wait. I haven't figured it out. If you do, the money is well earned.
