Just like with most forms of eczema we respond differently to treatments. We also seem to have variable triggers. We also have variations in symptoms, for example with GD some have mild itching, some have no pain and although the standard rash area is torso some also get it up the hair line or down the arms and legs. I have seen photos and even the rash papuales are not the same size for all of us.
Has a sugar free diet (which kills residual yeast residing in colon that raised the inflamation in your body) been tried? It definetly helped calm one of my other forms of eczema. The cilantro did work for me with GD, but I had also been on the sugar free diet for a year and perhaps that made a difference. It takes months to kill off all the yeast and yeast is easily resurrected if yeast fueling foods are reintroduced. Read The Yeast Connection Handbook by William Crook MD. Available on the internet, Amazon. Not complicated like the Karen Fischer diet for eczema and also the book is cheap compared to hers.
This diet calmed my internal skin so much I no longer required my annual corticosteroid shot to stop the relentless internal burning, zapping and stinging, yet it only helped for about 10 months before it would build up again and require the shot again. A treatment, not a solution.
