I know I had Covid. Positive home test, plus ALL the symptoms. I was moderately ill for three weeks, and seemed to recover. But since the test was not recorded by a hospital or doctor, I cannot participate in any study.
Then, six weeks after I’d seemed to recover, I presented with all sorts of odd symptoms. For me mostly sensory. I have hearing loss, vision loss, tinnitus, hyperacusis, dizziness, and digestive issues.
When I was tested for antibodies, I no longer had any. It’s been over two years since my infection, so I suppose that is why. This virus does not seem (in some), to keep antibody protection.
I have friends who apparently have vaccine damage. No help for them either.
Still, at some point the studies may help us....if we last that long.
