I get a small bumpy rash across both of my hands knuckles every year around spring, which I believe is dyshidrotic eczema (I take antihistamines for hay-fever, so don't experience much itchiness) and doesn't bother me too much. I've tried changing hand wash/clothes wash/body wash to sensitive versions, without improvement.
The larger bump is a new occurrence this year, I've had it for a few weeks and it seemed to just appear at the size it currently is, it hasn't changed appearance, size or redness since I first noticed it. It's not sore or itchy and doesn't seem to be attached to anything underlying (it moves when I push it from side to side) doesn't feel hard or soft like a liquid is inside it.
Is it likely to be related to the other rash?
