It started as a bump on his forehead. Then he had a few bumps on his arm and now they are slowly showing up on the back of his hand and the top of his feet. They start as flesh colored like blisters and turn red and scab over. He has been sick with a cough and runny nose for 2 weeks now and we are getting over covid. I have taken him to urgent care and his pediatrician and both say they are unsure as to what they are. Both state they do not think it is hand foot mouth as he does not have sores in his mouth. His pediatrician said to let them run their course but he has more on his hand this morning. What could this be!? Is it bug bites?f
