I know you can't diagnose but would appreciate your opinions. Ds, 4 had small spots (like a bite) on his chin, back of ear lobe and neck. These didn't do anything except get less red over a day or two. Now he has a big, red spot like I imagine cp to look like. It has developed a crusty head and itches a bit. He had no others though and has not been unwell.
I've just sent him to school, was that a mistake? Opinions appreciated please!
