Anyone know what this might be?

So I am in college & during thanksgiving break I noticed that my skin started to get kind of itchy, so I'd scratch it, and then it would go away. Fast forward to two weeks later during finals, and it started happening again except this time when I scratched the itch it would spread all over, and I ended up getting these red dots all over. Does anyone have any idea what this may be? I have a doctors appointment, but in the meantime I'm trying to find some ways to relieve it, because my skin is very irritated. I've tried lotion, and different creams for itching. They work for awhile, but it comes back after about an hour. As I mentioned above I am in school, could this maybe have anything to do with stress? I know you guys are not doctors or anything, but any advice or someone who has something similar, and would be willing to share would be greatly appreciated!
