★★★★☆
Cold Showers or Ice Packs or Ice Rollers for skin work really well for Grover's Disease.
If you sweat and don't have a shower straightaway you will feel a slight crawling stingy feeling on the skin, this is a warning sign that your skin is going to break out.
I've found that you can exercise and get hot and sweat as much as you want but you must not let the sweat dry on your skin, wash it off as soon as you can.
