all my life i have had these little tiny dark bumps on my legs and thighs,but mostly on my thighs. I wasn t born with these bumps, but they came upon me when i was a little girl. Eveyone that i have asked told me it was because of lack of Vitamin D , i have no problem believing that, because i wear jeans all the time and my legs are rarely shown in sunlight, but i just wanted to make sure.
