So im 15 and worried before about this problem but only today looking closer did i become this less self confident. For a few yesrd ive had these tiny red dots on my lower legs, upper thigh and the back of my upper arm, they kind of look like goos bumps just they are red, but they are so so tiny about the size of a pin head and have a tiny bumb on some of them. I dont know what it is ive tried searching it up but nothing is helping and it takes forever to get a doctors appointment now are there any ideas?
