My Grover's first appeared in late August 2022, and I was diagnosed soon thereafter. I tried innumerable drugs as well as the cilantro/chlorella smoothies, but the only things that gave me lasting relief were prednisone and topical steroids, neither of which could be used indefinitely. This past August my dermatologist started me on Dupixent. It took approximately six weeks to take full effect, but I have been itch free since. I have suffered no side effects and no injection pain. It saved my life.
