I had first thought it was an Eczema flare up (and who knows, it could be) with all the stress in the last week or so...
A coworker of mine says it really looks like poison ivy. Which I do have in my yard. And it's possible I wasn't paying close enough attention the other day.
It looks like it's getting worse. I will be adding tea tree to it today and let's hope that helps. (yes, it's one of the things listed that does help it). Whatever it is, it does itch.
