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

@gardeningjunkie-you say(said)"Because of this site we have read that cilantro works as a heavy metal detox ". I have posted on this blog but my posts didn't appear until much later. Here's my point, big or nothing at all: Everyone here in the 'Cilantro Club' has been experiencing results, mostly good, or even mildly good, which as a sufferer from GD is a god send. I'm one too. I'm writing this during the CoVid-19 Lockdown so access to fruits, Veg's etc. is not always easy. On to my query: Has anyone here ever thought that maybe, just maybe, the 'cause' of their GD could be related to a heavy metal presence in their body/blood? And maybe, just maybe since Cilantro is known to help remove toxic heavy metals, that is the reason for the vast improvements people are experiencing? I had a Total Knee Replacement done in 2018, and in 2019 I developed a rash at the site of the operated knee. Recently I opted to have a metal sensitivity test done and found that my Aluminum level was way high, over the High level even. To-date there is no explanation as to how and why. BUT in Jan. 2020 I started a new rash, thinking it was related to the other, but it turned out to be (via Biopsy) Grover's. I still don't know how my Alum. level came to be so high so I am about to 'gasp' try the Cilantro route and if it works and IF my Alum. levels also decline, then there could be a definite co-relation between GD & Heavy Metals. Just sayin'. My GD is restrictive, and intereferes with my daily life and activities, sleep especially as I now am lucky to get 3-4 hours of sleep a night. Itch/Scratch etc.
