Hello, my son who is one year and 10 months old has got blue/purple color on all his nails in his feet. His hand finger nails are fine. It is the 2nd day today and the color still remains. 2 days back he had vomited his dinner which came out through his nose as well. He passes urine normally and no discoloration. As in the current scenario with covid 19 and lockdown I am not sure if it is a good idea to take him to the hospital. I had also taken an oxygen saturation measurement using my smartphone which showed 95%. Could you please let me know your analysis.
