this same thing is happening to me. started in 2017 and still happens every year in the same spot and is the same size. however these little red blister/white head pimple looking bumps are itchy as hell and when i have scratched the area it rips off the top of the bump and its DEF not a white head. i wonder if u ever got your rash diagnosed?
I looked up dermatitis herpetiformis and it's linked to a gluten intolerance.
Hello,
Recurring itchy blister can be due to contact dermatitis, insect bite, viral infection, scabies or skin conditions like pemphigus or dermatitis herpetiformis. Without examination, it is difficult confirming a diagnosis, so please consult a dermatologist and get it evaluated. Treatment is diagnosis specific.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
You posted about a reoccurring rash in the same spot...I too keep getting what sounds like the same thing in the same spot. Did you ever find out anything? I saw similar pictures from a spider bite-but I find it hard to believe I keep getting bit in the same area without knowing it.
Let me know how you made out.
