Annoying Allergies: Elbow Edition

The last flare up was on my fingers in late August and they're doing fine now. Well, I do have a small patch of dermatitis right now on my middle finger, right hand. What's really annoying me right now is this because it's reeeeally itchy:

Patches on my right elbow. And by the way, have you ever tried to take a photo of your elbow with a camera that doesn't have a lens on both sides? Not so easy.  Anyways, I don't know what it is.... can't be from touching something today because my elbows have been covered... And it can take up to at least a few days for a reaction to occur which throws a curve ball into trying to figure it out. Who knows though, I get flare ups on my fingers when I drink coffee if that makes any sense. This is a typical spot for me... I just haven't figured out why I react on my elbow yet...
