My 12 month old who is competely healthy has these tiny, dark red spots under the skin of the soles of her feet. They arent itchy or painful, theyre flat. Shes been drinking and urinating a lot more and has loss a little bit of her appetite. Is this something serious?
Hi...by what you quote I think that it could be a simple viral exanthem, or it could be hand foot mouth disease. Whatever it is I suggest you show her to her regular pediatrician and get the opinion to be on the safer side. Hope my answer was helpful for you.  I am happy to help any time.
