Can pityriasis roses rash heal within 2 weeks?

Hi, 10 days ago I noticed a reddish papular rash all over my buttocks and part of my lower back that was mildly itchy along with a pink ovoid patch ~4cm on my neck. These could have been appearing for days and I wouldn't have known as I don't examine my backside in that much detail, I just noticed the skin felt really bumpy and got the mirror out. No fever, no other obvious symptoms except a slight sore throat.

I went to the Dr 5 days ago because although the papules were fading by using just sudocrem and wearing loose cotton clothing, there was the addition of a new pink macular rash appearing on one erm butt cheek. Naturally this was a delightful gp visit! I was told that the ovoid mark on my neck was too pale for fungus and was likely a herald patch and the other rashes were the start of pityriasis rosea. (differential diagnosis would be sweat rash on buttocks from recent overuse of heatpads and synthetic clothing (yes, I know, that was silly) and in my opinion potentially a tinea versicolor rash on neck.

I've been using a tea tree oil based natural body wash all over and calamine lotion on my buttocks and canasten cream on the neck patch (just in case). Buttocks have cleared up a lot now but I'm left wondering if:

1)I'm lucky and it cleared up fast

2)it wasn't PR

3)I'm still waiting for the full body rash experience

I hope it's 1 or 2 but are there any signs that the breakouts have stopped or can there be a lull before another wave?

According to the literature the rash clears within 2-18 weeks depending on which reviews you look at.

I have to say regardless of the cause of MY rash, it feels very unsatisfactory to visit a medic and hear that ultimately you'll probably have it for weeks and there's nothing you can do about it! How frustrating for everyone!
