My 8 yr.old son started with a fever last Saturday evening. Sunday he presented with red marks, most round or oval. Monday we saw his pediatrician and testing of the blood and a rapid strep test was done - all showed nothing. Tuesday a more accurate strep culture came back positive. The spots began to fade. We began antibiotics. Wednesday a sore throat began and a low grade temperature persisted. Today the temperature remains, but now there is a mark near back of his neck that looks like a hickey. Dark red, blotchy, and about an inch wide.
