I was diagnosed with Grover's disease back in October 2018. It started as a small patch on the back of my head and neck but then spread down to about 80% of my body by January. I was MISERABLE! I tried many different topical steroids and creams. I read through all the posts here and tried about everything suggested. I went Gluten and sulfate free too. None of which helped calm the terrible itch. The only thing that gave me temporary relief was Sarna lotion which I purchased at the drug store. Oral steroids would also stop the itch but as soon as I came off of them the rash and itching came right back. I also felt terrible side effects while on the Prednisone but for me it was better than the itching. I began researching other remedies and believe it or not I think I stumbled upon a cure! I read on a couple other forums that eating 1 bunch of cilantro a day had cured several people suffering with Grover's. So I decided to try it. I thought "what do I have to lose"? I was super skeptical, and I HATE cilantro. But I was also desperate. Within a couple weeks the rash was noticeably improved and within a month it is completely gone! I can't imagine how something so simple could do the trick and I am baffled that no doctor seems to know about this cure. I would ask that anyone suffering give it a try. It only costs about $1 a bunch and again, it couldn't hurt to give it a try. Hopefully you will all have success like myself and the many others.
