Does DH ever have a "head"?

[NoGlutensToday]

I have a red bump that I assumed was DH on my left temple. I have no idea how I got glutened -- I am extremely careful about what I eat, and when I'm not eating unprocessed meat/veggies/fruit that I prepare myself I am careful to pick items that are certified gluten free. (These latter items are quite limited. Basically some Bob's Red Mill millett, Only Oats gluten free oatmeal, and a couple other things.)

Noticed today that the bump on my left temple appears to be forming a head. My understanding was that DH didn't do this.

I'm wondering if this happens to be something other than DH, and just happens to be appearing in a place that I used to get DH. I have dry skin, and the family has a history of eczema, rosacea, and other skin conditions. As I mentioned above, I have no idea how I would have been glutened due to my strict diet. I also haven't experienced the other symptoms that I used to experience when I got glutened. (I have been on Dapsone for a while, but have been weaning myself off of it for the past year or so, and really only use it if I have what I think is a DH bump appearing.)

So frustrating! I'd attach a photo of my current bump but the camera on my smartphone isn't working.

It typically looks like tiny blisters that are clear (not white), and they are very itchy. They definitely come to a head, similar to acne, but are clear.
