Anyone with skin knowledge able to identify what this could be? It randomly showed up at a single bump, just 1 of the ones in the pic. Then through the course of a week, it spread out to what the pic shows. And it's been like that for over a month now. It hasn't changed in coverage any more than it did in the first week but it will start itching and kind of is a little flaky scab after itching it. I shower all the time and had recently cleaned my bedsheets so I dont think it's anything like that. Also no one else in the house has it. It is also only in this one spot. Please help!
