I have not yet had confirmation of what I suspect to be a problem with gluten (either a sensitivity of full-blown coeliac) but wanted to ask a question about dermatitis herpetiformis.
A year or so ago I had a single spot come up on my lower leg. It looked like a little round blister and was mind-meltingly itchy. It burst when I scratched it too hard, too close and the itching died down. However, it has left a slightly raised, purple mark where it was.
I understand that DH does not necessarily have to be symmetrical, nor does it have to be widespread but if you want it biopsied you need to get down to the GP while it's still active. I've not had anything quite like this since and I'm certain that it wasn't an insect bite of any kind.
Does this sound like it might have been DH? My skin generally itches like buggery most of the time and I occasionally get intensely itchy bumps but this is the only that I know of that's left a permanent mark.
I have tested negative on IgA tests but my diet may not be particularly high in gluten and might have skewed the results (breakfast is usually oats, lunch is soup and supper is about the only meal that contains gluten, and then only 40g of pasta).
Any advice much appreciated.
