I woke up and started itching a spot on my neck, just over the carotid.. the itching intensified and I figured to myself this was a bug bite, and sure enough I felt a raised bump. Looking in the mirror, it's around 1/4" across, and has 3 "fang" marks inside the bump itself, in a triangle almost. What kind of bug is this? I get these bites fairy rarely in bed, sometimes once every two weeks on my leg, and stuff like that. It doesn't seem like bed bugs as i've looked all over my mattress for signs, and found very few.
