I dont know what's going on but it feels like I'm being bit by invisible bugs I can't see all over my arms and legs. It burns and itches so bad and I am scratching myself to death. My husband COULD possibly be bringing no-see-ums home as he works on the beach, but nobody else is being affected except for me. This has happened a few times over the last few months or so, but tonight is the worst by far. Anyone have any insight as to what it might be?
