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

Study on the internet about the 5 Day Extended Patch Test, yes it is a full 5 days unlike the environmental test you have already had. I've had the True Test 5 Day Test twice. The kit is extensive, around $1,500 but Medicare covered it based upon my severe symptoms.
Once tested you will be given an id # so you can go to the ACDS Camp list program on which your doctor will have you registered with all your allergen's. This Camp list is updated every year and it lists products which do not contain your allergen's. It's a good starting place. It's the only reason I've actually found certain make up and grooming products safe for mel. Unfortunately sometimes I react to products which should be safe because they don't contain my allergen's yet I think that's because I wasn't tested for their additives, or I became more reactive over time. So still go slowly with new products.
I understand what you describe as little white bumps which are under the skin. These bumps are just dormant GD, waiting to explode. Mine are confined to my upper and lower back now and not the entire torso (except th sides and breasts which never had GD. If I go outside in the heat and sweat I can feel them get larger, but if I stay cool for a few days they will recede and not turn into a papuale. However mine have been dormant for so long they do not itch or hurt. The pain took over a year to go away even after my outer skin was totally healed. We're simply damaged.

Does anyone GD appear like this?

Yes but on torso. Sorry you're dealing with this. Great advice on this site. Don't put anything irritating or abrasive on it. Sweat and abrasion together can make it worse. Those little dots need to heal and it can take a long time - the less you touch them the better. Use the gentlest soaps (only if absolutely needed) and creams or none at all. Gently blot dry or let air dry. They just need time to heal. I have also found anti inflammatory diet and supplements (including the cilantro) and a daily anti histamine help. Some people on this site have found oral or topical steroids, antibiotics or anti fungals help.

I have just recently been diagnosed with what the pathologist states suggestive of Grover’s . I have been reading a lot on this forum and recently bought cilantro extract. Any advice on how to consume and or after affects?

I have been taking the extract for a couple of years. I just got tired of making the smoothies. Does it work? I'm pretty sure the smoothies worked for me, two years of them. I believe the extract may work, but not as effective as the fresh. I do take the extract even when the G D is in remission. I do believe that it helps limit the out breaks. I mix it in with juice, two droppers instead of one, once a day with no side effects. I will take it until I am convinced that the disease is in full remission, which may never happen. Good luck.
