Has anyone else observed what I have had in myself after Covid-19. I think it needs to be watched for in post Covid-19 patients. I had Covid-19 myself and although I started to have the symptoms of pneumonia and then a cytokine storm I was able to stop it successfully very quickly by using my own research on elderberry (Sambucus species) as an antiviral ,(antibacterial) and immuno-modulator. However I put on about 24 lbs , (11 kilos) in water retention. I was worried I had damaged my kidneys but blood tests showed happily that I had not, and my heart and lungs were as before the virus, my liver OK. My biochemistry is not great but I thought about it and read up some more and then tried supplementing with magnesium. I usually eat plenty of green vegetables so am not normally low on magnesium. But this has worked and in two or three days I am passing lots of urine and my weight is going down fast and I feel better . I am wondering if others suffering after they have recovered from the virus have also been depleted with (possibly different) essential minerals and may need these supplemented for a while.
