Concerned??

Lately i’ve gotten the spots on my legs. like 4-7 spots per leg. They look like pimples. They have like yellow tops like a pimple and everything. They’re also very sensitive. This is semi new. It’s only been happening for the past few weeks. I’m super confused and embarrassed. What are they?? Does anyone else have them? How do you get rid of them? I used to love showing off my legs but now i’m so embarrassed that i try not to. Please help
