About a week ago, a spot appeared on my low-back that is hard for me to see up close. I put myself into yoga-like position to take a picture of it so I could see it more clearly, and the only thing I can gather is that it's probably a spot of excema. I've never had it before, but I do have keratosis pilaris, and my mom has severe excema. I'm keeping an eye on it to make sure it doesn't spread, and it doesn't itch at all.
Just wanted to get some opinions and ideas of what it is. Thanks in advance.
