I have always had these litlle red dots on my upper arm and calve of my legs... they are smooth and not itchy, not dried out? What is it? And how do I get rid of it?

They might just be red moles. A lot of people have them. You can probably buy a cream online to get rid of them or go to a doctor to get them lasered. A doctor might prescribe a better cream for you

If they are small like freckles, I actually asked the doctor about them because I have them on my chest. He said they are known as "sun spots" he said it's just from being out in the sun HE THINKS, he told me nobody really knows what the cause of them are. He also told me they are nothing to worry about and sometimes they can get bigger if they get to big they can get scratched and bleed. They come and go he said.

My doctor told me it's nothing to worry about and he had them too all over his head (hes bald).

If you are concerned though I would see a doctor just to make sure that is what it is.
