Good diagnosis, Susan! Your identification of these tiny blisters as "pompholyx," the archaic name for dyshidrotic eczema, is most impressive. This form of eczema ("dyshidrotic" means "bad sweating," a plausible but discredited hypothesis) has no specific cause, but can be controlled by appropriate topical steroid and emoliient creams. Implicit in your question as to what this "really is," is the assumption that there is a specific cause, avoidance of which will eliminate the problem. Would that this were so. It "really is" pompholyx, and that's about all one can say about it, other than that you should obtain the most effective symptomatic treatment you can, and use it when the symptoms interfere enough with your wrk, which they will do at times, but not always.
Best.

Thank you very much for your prompt reply. I have been doing a lot of research to come up with the diagnosis of pompholyx. When I saw a dermatologist a couple of years ago, he said it was dermatitis and gave me Temovate Emollient cream. This really ate away at my skin, caused inflammation and seemed to make matters worse so I quit using it. Even an OTC 1% Hydrocortisone cream I tried (Cortaid) just seems to peel off a layer of skin, but is that desirable? The only thing that seems to be soothing is Triple Antibiotic Ointment but I know that doesn't make sense because it's not primarily a bacterial infection. The other thing I use regularly is Eucerin Cream. Any ideas about other treatments would be appreciated.
