It looks quite mild, but it certainly could be DH. I get blisters and red spots on my fingers all the time. The blisters are sometimes very small, just pore sized. Stingy, burny, itchy and blisters sounds a whole lot like DH to me.
If I keep my diet simple and lower iodine then my skin is better. I used to have that red rash you have, but that's gone now and what's left is more like purigo nodularis, but not exactly. The bumps I have will flare and blister if I get cc'd or have too much iodine. I am still terribly itchy in general, but I do believe that I'm slowly healing as it's...
Looks like DH to me. My rash used to look just like this before being gluten free for some time. My guess is that between the wheat noodles and the massive salt hit from the ramen flavouring is what caused this particular outbreak.
I'm also very itchy even where there's no rash. Drives me crazy to say the least.
