Maybe four or five times in my life I’ve had an eruption of little itchy/sore bumps/scabs on my forehead and a couple of times on my scalp. Back when i was a child I was told to apply iodine to it and eventually it went away. I always thought it was something like a cold sore because there was herpes in the name but I didn’t understand the diagnosis.
So, its happened again out of the blue and googling it looks exactly like Dermatitis Herpetiformis and I’m thinking that the name is where I got the idea about herpes from. However, it’s actually not linked to herpes at all but an autoimmune response to gluten and is very closely linked to coeliac disease. Weirdly, iodine apparently exacerbates it!
It’s only a very small patch and only happened a handful of times, but i do also have extensive psoriasis, which is a different autoimmune skin condition. Should i go to the doctor? A same-day emergency appt is very difficult to get and seems unnecessary, this is hardly an emergency. But, if i go for a pre-bookable it might have gone by then (it’ll be well over a week). I dont even know if i should bother the GP at all…
