HELP!!! I've been hit by a plague

Bummer, I've been harvesting a plague on my face!!! I dont know what I have but it all started with some rash that started at the chin, only a little. Slowly it encrouches to my entire chin leaving it a little reddish and itchy. It feels bumpy and rough to the touch. It's also dry and peels abit after shower. Then it spreads to the sides of my nose. Also rough to the touch. They look more like goosebumps I think. Unfortunately, that day, when the plague hit my face, I was busy packing up some stuff. So, dust didn't help the situation any better. At the end of that day, I had a shock when I saw tiny bumps around my eye area too and some along the browline and my temples. These bumps feel like normal skin, not rough but can be alittle itchy at times.

Anybody knows what is this that I'm having?

I've applied a hydrocortisone 0.5% on the rash/bumps yesterday night (Day 2). Today, Day 3, the rash is not itchy anymore but the bumps remain. Chin is not that red anymore.

I will update you more on what's happening. I'm planning to rough it out alittle and if it doesnt clear up anytime soon, I will be running to the dermatologist say, in 3 days' time. Hopefully it's nothing bad. Wish me luck. Meanwhile, please let me know if anybody out there knows what this is all about? Please!!!
