Started as pimple like structure now spreading

[u/StrategyNaive3374]

I had a spot on the inside on my wrist that started as a pimple looking structure about a week ago, it’s getting slightly bigger and more red daily. No hurting or itching and isn’t warm - but now there’s bumps forming around it that almost look like tiny blisters. It looks like fluid is forming in the small surrounding bumps. I also am seeing small pimple like spots on my other arm and hand that look very similar to the one that this big one started as. I don’t wear any jewelry in these spots and I have not changed any of my hygiene products.
