Everything I have read since 2007 about Grover's says Prednisone is not a good option as it will make your skin thin. There is no one solution for everybody. Gabapentin worked for me for 13 years but it just stopped working and I have been itching again for 3 years. I take Hydroxyzine to get to sleep at night and Eucerin Itch Relief after showers to get some relief. Lots of people have good luck with Dupixent if they can get it. Other people swear by Cilantro and Chlorella smoothies. You can research this site and look at the Facebook page for Grover's Disease and find many things that work for some people. Sorry, there is no magic bullet.
