This morning when I woke up, I found an ichy bump by my wrist. My nurse says I got bitten by a bug while I was sleeping. But it can't be a bed bug because I don't have any. My bump is round, kind of firm, the pores are enlarged, it's itchy, and it was pinkish. It's also about the size of quarter or neckel. What bit me you guys ? I'm afraid to go sleep on my bed.
