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

Hello! I've been following the comments on this support group for the last few days as I was very recently diagnosed with GD. I'm very curious to know if anyone has related theirs to Covid or the vaccine? My flare ups just started I'd say about 2.5 years ago - around the time that I had the first shot (never got a booster) and then I had Covid a few months later. I've never had any sort of skin disorder before that so it's the only significant change that I can think of.

Don’t wear underwire bras! Put max strength desitin which is 40percent zinc under the breast line after each shower, be sure to dry skin thoroughly first!
