I have little white bumps on my arm
SO I have these little white bumps on my arms, it looks like there down into my hair. They just pop up all of a sudden and look like little insect bites. For instance if I just scratch my arm due to dry skin or something, they pop up and swell up. They aren't red or anything (besides where I am scratching). I was just curious as to what it could be. They sorda look like little zits, but they swell up when I scrath them. It is really weird. Anyone have any suggestions? I could use some help.
