Ref. the rashes. Most of them appeared right after covid did. I already had psoriasis, but they were not psoriasis. They were mainly on my arms and legs. Usually, one limb at a time. Sometimes it itched and was very red. Other times it looked like a big bruise that appeared abruptly. And, I don’t bruise easy. I also got covid toe twice with an oval plum colored spot on my big toe. I had no trauma to the toe. It didn’t hurt at all. I didn’t have swelling like you did, All of that left after about 10 months. I can’t be sure it was due to covid. It’s my belief though.

My ENT diagnosed my post covid syndrome due to smell/taste disorder. I also had Vitamin B12 deficiency that I continue to treat. I also had nasal congestion, hair loss, insomnia and some nerve/sensation issues. Most have improved. I would say it’s difficult to know the cause of my ailments. I consider it could be anxiety, post covid, vitamin deficiency or something else. I just try to use good nutrition, exercise and treat the symptoms. It can be frustrating. I read some people are seeking treatment at post covid treatment centers.
