I think my dc has slapped cheek, do I need to go to the GP ?

I don't want to really, I only go to the GP if really necessary.
DC has the signature red cheeks and a rash, have done the tumbler test on rash and it's fine.

He seems better than he was yesterday, we are venturing out to the woods near our house for a walk, it's pretty deserted and no chance of bumping in to anyone so won't spread it, pretty sure he is not contagious anymore anyway, but he is well enough to want to get out, is the point I am making.

He doesn't feel hot to touch and is winding his brother up - so seems to be on the mend, it's just having a visible symptom of illness like the rash makes me feel guilty about not being that worried.
AIBU ?
Would a good Mum take him to the

See, the little toad just pressed send. He must be ok
Would a good Mum take him to the GP is what I was going to say.
