Ah, the good Chief has made his diagnosis even more specific and that would be my exact diagnosis as well. I am trying to find a picture online. I cut my blisters out this morning - sorry, that's gross, but you are experiencing the itch and you know how bad it is. When it gets bad enough I have to clip the little blisters with the side of nail clippers to get them to drain and the itch to go away. I get them on my fingers - particularly the middle finger of my left hand.
So here's what you can do to help clear them up:
First, don't scratch. Eczema has an itch-scratch cycle where you itch, so you scratch, which makes you itch worse. Another reason not to scratch is because eczema sufferers tend to have high levels of staph bacteria on our skins, so if you break the skin, you are not unlikely to get an infection.
Don't take long, hot showers. Just quick, lukewarm showers. Avoid soaping up the itchy areas, and immediately follow the shower by patting off the affected areas and then applying a very mild lotion within three minutes of getting out of the shower.
Wear cotton socks or go barefoot if you can - don't have anything rubbing that area though. Did you wear sandals with a metal buckle there or something?
If you develop widespread ezcema you may have to make lifestyle changes. I've had to change a lot of things since developing eczema five or so years ago.
Out of curiosity do you also have hay fever or asthma?
