I know medical questions aren’t allowed on this subreddit, but this one was so mundane and yet so oddly specific that I figured this was the best place to ask.
My left middle finger keeps getting an annoying, itchy rash that is covered in tiny pimples. It’s worst on the sides of the finger. I know eczema is a thing, but I’ve never heard of it being specific to one finger.
The closest thing I could find is maybe dyshidrosis, which can give you itchy in the side of your finger. but I think those bumps have fluid in them like blisters, and I don’t think my bumps have fluid.
If it helps, I usually wear rings on my middle fingers, but I haven’t worn any in a while, and my right middle finger is totally fine. I’ve been having problems with this specific finger getting insanely itchy rashes for over a year or two.
Did you put some sort of petroleum jelly like Vaseline on the hair follicle area of the finger? For me, if I do that, I can get backed up pores that create small “pimples”. If it is on the palm side then I don’t know. I learned also that I am allergic to Neosporin so it might be that if you have been re-applying it. If so, it won’t get better until you stop.
