Trouble identifying a rash

[Blorp]

About a month ago, two days after a physical exam including blood and urine tests, I began to develop a rash on my wrists, top of feet, and ankles. I left it alone for about a week and it began to spread more often the top of my foot, down to the bottom of my feet, over my palms, and along the sides of my hands. At this point, I sought help from a dermatologist.

The dermatologist said it could be any number of things, but it's hard to tell what exact. He noticed the over a year ago I had a similar rash localized only on the top of my feet, and that some steroid cream cleared it up, so he gave me a prescription. He ruled out other more serious illnesses like Rocky Mountain Spotted Fever since I had no other symptoms. Even now I lack a fever, flu like symptoms, fatigued, etc.

I used the cream for roughly two weeks, and it didn't appear to be doing a whole lot to clear up the rash. It was a little more faint, but seems like it was stagnating. I stopped for about one week out of what I assume was sheer stupidity, and of course it got much worse. The rash on my feet is gross to look at, the rash on my hands has spread around to the top of the hands and over my fingers. It looks better than the feet, though.

I saw the dermatologist again, they took a biopsy, blood, and urine. Urine and blood tests were done through the hospital, the results haven't made their way to my dermatologist yet, but the hospital called and said nothing was abnormal. Biopsy results are still unknown. I've begun using the cream again but have only been on it for about three days and haven't seen any improvement (granted I know it'll likely take longer than that.)

I'm trying to figure out what's going on. Here's how it appears and some symptoms more broken down:

The rash is localized only to my wrists, palms, fingers (all around), top and sides of hands. It's also on the top, bottom, sides of my feet, on my toes, and on my ankles. The rash seems more concentrated on joints, it's heaviest around my knuckles, and... feet knuckles? It appears more heavily on the sides of my hands and feet than it does the top or bottom of both appendages.

The rash is a light pink, spotted, with very small deep red dots here and there. In the last week those small red dots have become more numerous whereas the pink splotchy discoloration has become less pronounced. I've noticed a few very very tiny scabs forming on the top of my hands, I assume due to scratching. The rash was NOT itchy until just last week, and the itchiness has intensified each day. The steroid cream doesn't seem to resolve the itchy feeling for long. It provides relief for roughly an hour in that regard.

If I look at my hands from a distance in the mirror, it appears as if my fingers are red, with many tiny red spots making up the coloration. For whatever reason it's lighter on the joints of my fingers, almost not even there. My skin doesn't feel abnormally dry.

Every now and then heat starts to build up in my hands to a point I would say isn't quite normal, but it doesn't cause me pain. In general, I feel no pain from this, just an itchy sensation. I have no other symptoms of an allergy, though this time of year I would normally be coughing/sneezing. No fever, no fatigued, no other medical issues.

The rash feels raised on some patches of skin and flush on others. The splotchy pink portions are blanchable.

Not taking any medication besides some melatonin to help with sleep. I work during the middle of the night and am seldom out during the day. I have a fairly sedentary lifestyle as my job requires sitting for long periods of time, and I tend to play a lot of games at home. I try to stay active, get up, walk around my place, go on walks on my days off. I take a multi vitamin.

I don't know what's going on, I'm getting kinda stressed as I wait to hear the results of my biopsy, hopefully someone here can shed a light on this?

Bugs in your environment. Like cockroaches or something. I once heard of someone finding cockroaches living in his coffeemaker. You ingesting something you're allergic to.
