I have a bumpy patch on my left elbow. It has been bothering me for a few days, a bit itchy and bothersome. I grabbed a hand mirror to see what it was and it didn't look like any rash I had seen before. I got onto the Internet with mirror in hand and started researching skin rashes. I've ruled out eczema, hives, and hundreds of other rashes. But this resembles psoriasis, a very mild psoriasis. I'm convinced I'm right. It's the only diagnosis that makes sense considering the arthritis I'm dealing with.
