Am I coming into some money or just have allergies?

I’ve had itchy palms off and on for a few weeks. Not big welts or anything like poison ivy – although I thought at first it might be – just itchy, mottled palms off and on. I assume it’s an allergic reaction but don’t think I’m doing anything new. I’m eating more blueberries but that’s about it. Anyone have ideas? Of course, if it persists, I’ll go to a dermatologist, but it’s so non-specific and not terrible yet, just an annoyance, that I’d rather wait a bit.
