Yesterday morning I woke up with 8 little red bumps JUST on my left leg... 3 on my calf, 2 on my knee and 3 on my thigh... my boyfriend woke up with 2 or 3..... I woke up THIS morning with 4 more-- 2 on my shoulder, 1 on my arm, 1 on my hip,.... and my boyfriend had a few more...... My roommates have a pet but they keep up on his flea medication so they aren't flea bites.. But they itch really really bad so I thought for sure they were..... What are they? I don't SEE any bugs in or near my mattress..
