Very tiny, clear fluid filled bumps on finger?

I've had these bumps for a little over a month now, I haven't tried treating them in hopes it would clear up. Now I am worried because they seem
to be spreading(just on my one index finger). They are about the size of a pin needle poke, but they are bumps so so they stand out on the skin, I haven't popped them but they will with pressure and a clear liquid will come out. If they pop it becomes a little itchy for a while, and the skin around it seems to wrinkle. I took a shower last night and must have opened it up a bit cause some soap got in causing it to sting, which I think worsened it and caused it to spread since then ..
I should also note I've been doing some online research and haven't found any solution other than maybe pompholyx eczema? my aunty has eczema but I don't think it's pompholyx. And the pictures I've looked at look extreme. I also have very sensitive skin and am allergic to nickel(haven't been tested for but I'd break out wearing belts or cheap earrings even some laundry soap etc.). I just considered it may be an allergy today because I'm using this expensive gaming computer mouse I was given, and checked online to see that it is real steel, and I'm breaking out right on the fingertip. But I've been using this mouse for 3-4 months now so I don't know. And if anyone knows any treatments/remedies because it sucks to have to conceal this.
Sorry the question is so long, I'm just really looking for an answer before turning to a doctor if it just eczema.
