ever since last year, i would randomly get these red dots on both of my legs that would reach up to my thighs. i only get them on my legs and never got them on my arms or any other part of my body before. they're not bumps, just like spots on my skin. they're not itchy either. they're pretty tiny and there's a lot of them going all the way down on my legs. i asked someone about it and she said it could be that my capillaries burst... is that true? i'm really curious because if that's the case, why?
