COVID with absolute certainty affects the auto-immune system.
The first time I acquired COVID, it CURED my severe psoriasis. I had itchy, flaky skin on both knees for 20 years until I got COVID. After recovering from COVID, the skin healed completely! It has been three years and the psoriasis has NOT returned.
I had the worst ‘flu’ about 3 weeks ago and I'm OK, now. (I didn't get treatment or see the doctor, but I just toughed it out). It was a flu like no other and lasted about 5 full days. I slowly got back to normal. The psoriasis that bothered me for years is gone
The psoriasis was never really bad or extensive, just a small place behind my ear.... now it's gone
