East Suslove.
It's not completely red, just kinda rough.
It could just be a form of eczema or even a rash from an allergy.
If it's itchy use an anti-histamine cream but if you're concerned then visit your GP, a school nurse or even just a chemist.
You don't need to go with a parent to the GP either. Although, knowing Doctor's, you might wish to phone ahead and get an appointment (Although these can be set up to 2 weeks later) instead of turning up and having to wait hours.
Eczema is a winter thing.
It's not seasonal.
And even if it were, it's still February, which is Winter.
