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.
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.
