How can I treat dry cracked skin on my fingers?

[kellyst]

About 6 months ago, the skin on my point finger (right hand) started drying out and cracking to the point where it would bleed.  Shortly after the rash moved to my thumb right next to it.  Jump to today where I know how 5 fingers impacted - 3 on my right hand and 2 on my left hand.  I've tried treating it with prescription medication for eczema but it had no impact.  The same medicine helps eczema that I have on my foot (which I started getting just about a year ago.  I've tried applying Vaseline then wearing gloves.  The only thing that sometimes helps is covering it non-stop with band aids so it doesn't get any air, but the band aids are rough on my skin.  I've also tried giving up gluten.  I'm only 3 weeks into that but it's just spreading more.  I am female and in my 40's with skin issues that I never had as a youth.  Any thoughts?
