Unexplained hives..

Haven't changed any soaps in the last few days or anything that comes in contact with this area. & have some on my forearms as well. They get worse at night & more pop up & yes I've checked for bed bugs or anything else that might be biting me.. so frustrating as it's extremely itchy when I first wake up..

**Husband doesn't have any & neither does our 2 girls & the oldest has a problem climbing in bed with us in the middle of the night.
