I totally understand. That's what dh does. Not to say other things don't do that but I don't know why derms are SO resistant to ruling out dh by doing a biopsy for it. Doctors are so obsessed with doing all kinds of tests to rule things out but when it comes to celiac or dh they suddenly know it couldn't be that & shut down on the notion that it won't hurt to at least rule it out then. Grrrrrrrrrrrrrrrrrrrrrrrrrrr! Stamping feet & pulling out hair.
