I stumbled upon this post this morning and I was curious as to what "dishydrosis" was. I went to the Mayo clinic website. I have been dealing with this rash on my thumb for the past six months, it goes away for a week or two and then comes right back. Intense itching and little bumps, then the skin cracks open and hurts like heck! I had one Dr tell me it was scabies I used the cream they gave me, it didn't go away. Its only on my thumb. If you'd like you can pm me I'd like to hear what you do for it. I'm calling my Dr on Monday with the info I've found on the internet, thats pretty sad when you have to self diagnose yourself, isn't that what Dr's get paid for? Hahaha
