It itches really bad not painfull until i scratch one white bump and some more in a roll, is this a spider bit

well, it sounds like it can be a spider bite, or some normal insect bite. But spider bites usually sting or is sore and stays sore when you first get bit. And spider bites dont usually itch, they just sting. But if you're not completely sure, and if it doesnt go away on its own, you should visit a doctor.
