I Have Bites Literally All Over My Body. I Get

I have bites literally all over my body. I get bit by mosquitos every summer, but this year it's really bad. I'm in a lot of pain, and so itchy. No one on my house is getting bit other than me. I've checked for bed bugs, none. There are no fleas or flies in my house. I'm confused. I've never had so many bites on my body, they are literally everywhere. Please help!
