I did get an xray when I went in for fluids. Got a report from the doctor over a week later that there was suspicion of covid pneumonia. I'll look into these supplements, thanks.Fink, the covid rash is not uncommon. Did they do a lung xray to make sure there is no secondary bacterial pneumonia from the virus? The lingering cough is common and hopefully irritation but an xray needs to be done to make sure. Some post covid things that could help are NAC , fish oil, milk thistle and turmeric. Covid stresses the liver a lot. The liver takes out the trash in your body. B vitamins and milk thistle clean the liver. The NAC will help with lung repair and there is a cough syrup called Umbca that can help that lingering cough. Amazon sells it. The fish oil and turmeric are for inflammation and that is a major covid issue. . My son-in-law is on this regime since his post covid pneumonia hospital stay and he feels wonderful. I posted an article about covid brain inflammation. I had similar brain issues for about a week. I could not concentrate and my emotions were as you described. The white blood cells in your spinal fluid are fighting the virus and it causes swelling and that causes weird brain stuff.
