Not much is known about Grovers Disease, but what IS known is that it expresses itself on the sweat ducts. The skin tissue in the sweat duct area just sort of falls apart (sorry, didn't intend to get technical...joke). I'm sure the ice treatments don't address the root cause of the disease, but they have mediated the effects for me. Cold treatments in general!

I also have a evaporative-cooled mattress pad under my sheet (air passed through water cools the water and it is pumped through tubes in the pad). It works well to keep me from sweating at night, though you have to experiment with it to get that cool but not cold setting.

Start your showers just warm water (it won't bother the condition if it is only warm), then turn the temp down in steps until it's too cold to tolerate. Like boiling a lobster in reverse, you don't notice the temperature change and find yourself standing in water that would make you scream if you just stepped into it.

They make evaporative vests, but in my experience these are not effective. The ice vest is.

I would not dismiss possible a relationship of GD to drugs and I wouldn't leap to make correlations either, but I doubt it. I had a shingles vaccine probably 15 years ago, but just got Grovers in the last 2 or 3. I'm sure many people who have Grovers did not get the vaccine. And, I'd hate to have shingles and Grovers at the same time, so weigh this in when you decide for yourself.

We get Grovers at a time in our lives when things are happening to us. I mean, since I turned 50 I've had intestinal, colon, prostate and skin cancers, a heart attack and valve replacement, and more. Now Grovers. Things happen as we get older. Sucks to get old, but I wouldn't have it any other way.
