I have tiny (about the size of the tip of a pen), painless red dots all over my body. They are mostly concentrated on my forearms and upper arms with some on my thighs. They don't seem to have any pattern to their placement and they show up suddenly. I have about 20-30 of them all over my body. I've had them for a few years but recently the amount has greatly increased.
I most likely have an immune disorder (I have never been officially diagnosed, but it is very likely I have some sort of immune disorder). I do have many allergies and have had eczema since I was 4 years old. I was wondering if the dots could be a sign of something more serious and if I should get tested the see if I have an immune disorder.
