weren't rashes but the skin was peeling!

2 nights ago I was about to sleep and felt something 'crawling' on the skin in my ear.

I thought it was a small piece of tissue so I just took it and threw it on the edge of my bed. I woke up the next day with what i thought were rashes on my earlobe, and the part near it. It wasn't itchy, just tender. Then I realized they weren't rashes but the skin was peeling. I felt the inside of my ear (not inside the hole yea?) and there were blisters i thought were pimples.

Now (3 days later) there's yellow stuff that formed crusts on my earlobe and the skin inside my ear. I don't know what might have caused it. But my left ear is swollen and the earlobe stings like there's no tomorrow.

What could've caused this? and are there any effective home remedies I could try?
