I have little red dots near my ankles and collarbone, they don't protrude, itch, or hurt, but i've had them for months and want to know what they are.

Dermatology question: & very dependant on explicit details of appearance (best evaluated in person), details of individual characteristics & history with potentially many important key questions. You might get some clues researching https://www.google.com/search?q=red+skin+dots, yet may also mislead yourself with fears about possibilities which don't fit. Best also seek out someone worthy of your trust for assistance.
