I have been getting these really weird like spider bite looking bumps, at first I thought that is what it was.. Because I got a new one ever time I woke up, so I washed my sheets, just in case, then I didn't see anymore bite looking bumps on me for a day.. Then I realized the next day that they started poping up out of no where ? They look like spider bites, they itch.. But they happen out of no where.. Idk what it could be? Any ideas?
