Red bumps/rash on inner right bicep

[Newwby]

23yo male.
I've got a rash on my right arm (inner side of bicep) I've never seen before, it appeared yesterday and consists.of red slightly raised bumps of 1mm to 2mm-3mm across. My skin surrounding the bumps isn't red or inflamed and the rash isn't itchy in the slightest.

The bumps have stayed mostly confined to an oval, almost circle area but I think (can't recall) the area has gotten slightly bigger since yesterday. One or two bumps have appeared on my inner forearm on the same arm now - a fair bit further down than the rest of the rash. It's completely dry and the bumps fade if I press on the area.

As of today (day 4) it's now spread to the backs of my hand, most of the bumps/spots in places that aren't the original location (inner right bicep) are barely raised or not raised at all and more pinkish than reddish in colour.

It might not be eczema but for someone who's hd eczema for years and years I recommend hydrocortisone ointment. Not that 1% over the counter garbage that claims to be "maximum strength," ask your doctor for a prescription, you'll get a 2.5% hydrocortisone ointment which should bring the swelling down. If that doesn't work try for a cream that helps treat ringworm. Best of wishes.
