My 19 mo DS has had these pimply bumps on his upper arms since the summer. I thought it was prickly heat, but it's not hot anymore. They aren't red or even pink, they are almost like goosebumps but they never go away. I tried using some lotion on it, nothing happened. Any idea what this is? It doesn't seem to be an allergy of any kind, and it doesn't flare up and go away or anything. It's just there. He doesn't seem to be bothered by it.
