What is this sudden red rash spots?

I have developed a few red rash raised spots on my right bicep, forearm and on my left bicep. The have been there for a week. Not itch, no blister. Just two of them seem to be "flaking"  6 of them are like a cluster of bumps and one is just a single spot.

Almost five months ago I have a scare with an unprotected oral sex encounter I had. I did full blood tests at the two day mark and then at the 12 week mark. All negative. Never had a rash at all until now.

1.- What can this be?
2.- Should I be concerned?
3.- My dermatologist cant see me until next week.

I hope the pictures work.

Thank you in advance.

Possibly an early pityriasis rosea. Do consult your Doc.

So they don't look like it's herpes?

[maatson]

The pattern in Herpes is specific, with vesiculation, which I do not see here.ok?

I went to the doctor today. Dermatologist. He saw it and immediately said it looked like pityriasis rosea. Prescribed some steroid cream and scheduled for three weeks to follow up.
I got back home and now I have more spots.
Is this normal?
Thank you.

It is expected that some new spots crop up, but disappear in time, no worry. ok?

Thank you so much.
I appreciate you taking the time to help me.

Can the spots from PR be single bumps? Or are they all groups of bumps together?

I developed some single bumps all down my forearms.

[maatson]

They are single bumps, and not surprising that new lesions do crop up from time to time.
Quite bothersome but PR settles in a few weeks.

Again, thank you so much!
