I too have the dots, under my skin, they are not raised, like tiny bruises, mostly from my knees up, but only over my upper legs, as far as I know. They are red, sometimes purplish red and there’s loads of them, evenly dotted around, about the size of a dot from a ballpoint pen.
I didn’t know if they were caused by my support hose, which I wear 24/7 to help with the POTS. I have read that they can be a symptom of Vit C deficiency (interesting, as vitamin C is required to make collagen too, which us EDS’rs have problems with), so I have ‘upped’ my intake of vitamin C and they have subsided but not gone completely.
