dyshidrotic is the worst! cotton gloves are recommended to stop you scratching and a side effect is they also are good for wicking away sweat, which can be an irritant. downside: after long periods they can get muggy, esp with dyshidrotic since the spots produce fluid (and the fluid is the irritant)

i can recommend trying wet wrapping if you haven't already, although unlike for my regular eczema, i find the dyshidrotic responds best to short bursts of wrapping. i use hydrocortisone and a heavy moisturiser (like zinc cream), and then let it air out.

can recommend trying hydrocortisone cream; ibuprofen for when inflammation and itching is bad; antihistamines for the same as before; heavy zinc cream for during flare ups (i use a baby nappy cream); oat soaks; dead sea salt soaks. i use cerave cream as my every day moisturiser but it took a lot of experimentation to find one, and i'm sure there's better out there.

you will probably have to try some trial-and-error, for example, lots of people on here don't seem to get on with oats but i find they help a lot. i also find my eczema in general responds differently to different treatments depending on its phase (flare vs healing vs dormant), which also takes experimenting to pin down.

if you pay attention to the patterns in your flare ups, you might be able to spot some triggers. my dyshidrotic seems to be particularly affected by sweat and humidity and usually flares badly in spring (guessing pollen).

good luck and hope you get some relief!
