For awhile now i have had a rash between 2 of my fingers. i have ecsema and i know its not that. it itches sometimes, any ideas of what it might be?

Still may be eczema: Eczema on the fingers and hands doesn't have to look like the dry, crackly surface skin texture of eczema elsewhere. Fingers can have itchy flesh-colored bumps, called dishydrotic eczema or dishydrosis. The treatment is as in eczema, with Hydrocortisone cream 3 times a day for a week. . . And if the rash worsens or isn't better, one should see a primary care doctor or dermatologist for evaluation.
