I've done a lot of research for my husband who has undiagnosed DH. He's had it for the past 20 years but has been misdiagnosed and seems like the photos in the DH photo bank match perfectly. Anywho, I wanted to ask a question on his behalf as I have not seen this topic (although I have read many posts but not all).
Does exposure to sunlight, wearing sleeveless shirts, worsen the blisters or itchiness?
My husband says whenever he is in direct sunlight for too long he starts itching more, blisters appear or become more raised, etc.
Your input is greatly appreciated. Thanks!
