Hi - I am a 65 year-old woman, andI was just diagnosed with Grover's Disease by a punch biopsy. I've had the rash for 6 months now, and it came on pretty much overnight. Traveling from a vacation in Denmark, back to California. I also have Hashimoto's, and have been on a very specific diet for the past 4 years, called AIP, Autoimmune Paleo protocol. While in Denmark, I ended up eating several things off the diet, including gluten. So, not sure how much diet contributes to GD. Though, it's hard to imagine the symptoms could come on that quickly - I felt fine the entire 3 weeks I was in DK. It seemed to come on during travel home. I am also wondering if it could be autoimmune related in any way.
