@h2998sc Last August I took this article with me on doctor visits: https://www.sciencedaily.com/releases/2025/08/250811104235.htm It lead one doctor who was trying to determine why I kept testing positive for Covid 2 years after I had Covid D to do testing of my blood and on the long strings of yellow drainage from my sinuses. This lead to the discovery that my immune system had been completely compromised. This disfunction discovered problems with the C4 and C3 and almost no CD8 T-Cells. In summary, my body could detect the spike protein, hunt them down and blow them up, but with no CD8 cells to transport the fragments safely out of my body, those fragments survived and then replicated throughout my body. And, the key discovery of fragments of 'spike proteins' from lingering viral reservoirs or active replication in the yellow drainage was the result of my immunity dysfunction. I had become a walking replication factory for spike proteins. The worst was in the 'brain drain' sinus which is the Sphenoid cavity. Brain fog was tied to a clogged Sphenoid. That drainage was impacting malefactor sinuses and closing them up, causing headache that felt like I was having a stroke, killing my taste buds and enlarging my tongue. That yellow drainage destroyed my biome in both upper Gi and lower tracts. My health was so bad it actually impacted my liver because the spike protein were also deposited there. I found treatment options from just an exam of my Sphenoid and a blood work up. I'm almost back to my normal pre-Covid self.
