Grover's Disease: What works to help find relief?

I'm new here and new diagnosis as of yesterday. Had what was assumed to be a scabies infestation late January, though the rash began mid December. Back then I worried it was bed bugs from travelling but they were ruled out as were fleas, my next worry. By the time I went to the doctor it was inflamed and intensely, painfully itchy spots from my neck to my knees. I was treated for scabies without mites actually checked for so it may have been Grovers from the start. I was given Permethrin cream twice then ivermectin a long with steroids and it seemed to improve but came back quickly. Punch biopsy led to the diagnosis and now I'm seeking advice on managing it till it hopefully resolves

Suggest you might review entries here for last several years and find what has given some relief to others. Hope you may find help (less side effects).
