What does it mean if I keep getting rashes/pimples, but only on one finger?

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.

You should see a dermatologist for an accurate diagnosis. They are far more knowledgeable than us and can suggest treatments.

I used to get these regularly on my fingers and heel of my palm for years.

Once I changed soap and shampoo away from my wife’s fancy stuff to normal, basic stuff, it’s all come right.

Go see a doctor. They could be warts, there are many types of warts and some get very itchy. Or it could be chillblains. Or it could be something else. And you can have an infection on top if you’ve scratched it often. But I am not a doctor. Next time go for a checkup, which might be a good idea if you haven’t for the past two years, mention it. Take photos of the finger if it’s a thing that comes and goes.

could be anything, even allergies or an infection.

I’ll say it; could be HSV.

Sounds like dyshidrotic eczema. A primary care provider should be able to diagnose that (rather than needing to see a dermatologist necessarily). Can be treated with steroid creams.

Stop fingering your mom. 😉 (Sorry, couldn’t resist)

Thanks to this thread, I learned that I definitely have dyshidrosis. I gotta call a dermatologist now.

Drusas ,

To be a little clearer, it's dyshidrotic eczema.

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.

Go see a dermatologist.

A few years ago I would get patches on the back of my hand that would itch and have tiny blisters. They were persistent and over the counter ointments weren’t helping. Finally went to a dermatologist when they got unbearable. The first one I went to prescribed an ointment that sorta worked, but not that great. Ended up going to a second dermatologist when I found out the first one was an anti-vaxxer.

The second one was on top of his game. He straight up said the first ointment wasn’t a good one to use and prescribed something much better. It knocked out the spots and itchiness after a week or two. I’ve had a couple of minor flair ups since, but the ointment eliminates it pretty quick. Haven’t had any problems for at least a year.

If you can, go see a dermatologist.

So, what was it? I get a steroid cream (triamcinolone acetonide 0.1%) but I’m curious if there’s an alternative. I try to use the steroid as little as possible, only applying it when it gets particularly bad.

Yeah, that was my second prescription. The first one was clobetasol propionate which you are only supposed to use two weeks on, two weeks off. It didn’t work very well.

Edit: for over the counter I use Eucerin eczema relief. I also have a jar of CeraVe, but I haven’t used that in a while. I only have to use them occasionally.

What are you doing with that finger? Not joking.

One of many possibilities :
