I was diagnosed with Grovers Disease in October 2019, a relatively mild but still very annoying case. My dermatologist prescribed triamcinoline acetonide cream, 0.1% which has provided some relief. However, and perhaps entirely coincidentally, I also experience the onset of sciatica in October 2019 as well [a re-occurring problem for me]. Yesterday, April 3, 2020, I had a lumbar spinal injection for the sciatica, and since then, the itching has significantly reduced. I can find no research suggesting any correlation, but I have found this striking, and welcome. It may just be coincidental but perhaps not. I have not yet noticed a reduction in the Grovers 'spots.'
