I work in a lab- and we are finding this in acute covid and long-covid patients. We use a thioflavin stain that fluoresces only when a deposit adopts amyloid-like structure. In other inflammatory diseases we have to add thrombin to a blood sample (like asthma) to kick off the process in the sample, and then it will bind and fluoresce. In acute covid, thrombin isn't needed to be added to the sample because the spike protein itself starts the fibrinogen amyloid microclot process.

With long covid, we're seeing spike protein production months out, and unfailingly these patients are still having some combination of things like brain fog, heart palpitations, fatigue, low oxygen, shortness of breath, digestive problems, kidney problems, etc.

It's part of the reason that I'm convinced that this damn virus is a weapon. There's no doubt in my mind that there's gain of function at play here.

I'd take B vitamins, too, if you aren't already. B6, B9, B12 break down fibrinogen by reducing the homocysteine (amino acid). Nattokinase is great, and so is serrapeptase. I'm glad that it sounds like you're on the way to fully recovered!
