Should I get a test?

I seem to have come out in a bit of a rash, nothing major but sort of bumpy and itchy on parts of arms and chest. I'd put it down to working outside over the weekend and maybe I'd been bitten, but now realise a rash may be a symptom.
I've absolutely no other symptoms, but should I book a test anyway?

Have you googled cironavirus rash and compared yours to the images?

There's some similarity, but nowhere near as many as some of the examples. I think I'll take some anti histamines and see
