About days ago, we just moved to Canada. And it was really cold, and my legs started to itch so much. I applied rubbing alcohol, and It haven't itched. The following day it was itchy again, so I took a warm bath on the tub, and I realized that there were tiny red bumps on my legs. I don't know if they were present the day before I noticed it. But when It started to become itchy, it was only red and irritated patches. After that, I noticed the same thing over my upper arms, but not as much on my legs. I think I scratched too much and I wounded it. Today it's healing, and some of it are taking off. And btw, I just wanna ask what these goose bump-like bumps over my my upper arms and upper back below my neck. I've had them ever since adolescence, and I wonder if it's serious or not. And also, I have these pimple-like bumps on my chest, not much of them. But I'm really anxious about it. I'm only 15, and that's about it. Thanks in advance
