Dyshidrotic Eczema (or Pompholix) is quite different from other kinds of eczema. What you have (Johng and Alixmama) is not what KYSufferer has. I know that because I do since 12 years and treatments effective for you don't work for us.
I've been to many doctors and dermatologists like him/her and aside from the first 4 or 5 wrong diagnosis, I was eventually diagnosed with cronic dyshidrotic eczema.
It only affects palms of hands and soles of feet.
Steroids, cortisone creams only help to relieve the symptoms a bit when it itches like crazy, especially at night. (Good alternative to the thought of wanting to chop my hands off in order to stop the pain).
Put vaseline at all other times to trap moisture in, otherwise they'll crack and bleed in the PHASE 2. Other moisturizers (even the dermatologist recommended) contain some irritant stuff that I cannot apply when there are open wounds. So, I stick to a lil' bit of vaseline at all time (wipe excess with soft cloth) even if your hands look fine and don't seem to need it.
Keep your hands clean, minimize contact with water and soaps (I used to have to wear double rubber gloves secured with rubberbands when I had showers!)
At the moment there's no cure, they don't even know the cause, but thu error and trial I recovered from it not by dealing with the symptoms, but going to the rooth of the cause. I tried many healthy diets/lifestyles to solve this problem because nobody seemed to be able to help me and after some improvements with the vegan, then macrobiotic (very complicated) diets I moved to eating 100% ORGANIC raw food. With very rare exceptions. Then lately I have done a 7 days water fast. IT IS GONE!!!
In my researches I came across many articles in the past that said how eczema like other stuff in the body is simply its desperate attempt to remove excess toxins. When our body is overloaded with toxins it will try to isolate and eliminate them as much as it can to the extremes of cancer.
I hope I've been useful to you KY. You can contact me if you want to ask me more on this.
