I am very grateful, @atma.love, that you are answering me this way. I was not going to look like an expert and just shared what happened to me personally with others. I will change my post in your respect, of course.
I am also happy that you managed to cope with corona (if it was that). Why do not you share this your experience with others in a post? It probably works at some early stages. In my case the lungs were affected dramatically. So, we are, probably, just talking about different things. But covid19 IS real, I know at on my own example. I wish you full recovery. Thank you for your kind reply.
