My lovely but extremely silly DS nearly 15 (well tomorrow actually!) came home from school yesterday with flat, red under the skin type rash/spots. He said he was playing the 'red face' game ! For a second or two he couldn't remember where he was but recovered quickly. He went to see matron at school who said he'd probably burst blood vessels. DH picked him up after school and he has been absolutely fine ~ except for the rash. Any ideas? How long is it likely to be there? and any lasting damage... He wont be playing that again in a hurry!!
