I have this thing that maybe an allergy although i not know what really causes and triggers it. You know when you like keep sucking your skin until there is like needle like red spots showing?sometimes i would get itchy and when i scratched and look i have these red spots showing sometimes near my armpit and arm.i searched online but all others not seem to exactly match since mine isn't inflamed or bulgy, its neither flaky or bite like...its like when you suck your soft part of skin
