What is this?? Rashiness

[ColourofMagic]

Just that really. My ds came out in this overnight. He's had a cold since Thursday and still has a cough but otherwise I thought he was on the mend. I tried the glass test but in all honesty I'm not sure if it disappears. Is it worth a doctors appointment?

Could it be heat rash? Could you ask at a pharmacy?

Not heat rash, he's been up for an hour or so and was quite cool overnight. Pharmacy's a good call though, I'll see if the local one opens before school!
