I have red itchy bumps on my neck, chest, torso (front and back), and legs. They are hard and blotchy. Imagine what it would look like if someone were bit by 1 million mosquitos. There are a couple that look like they have a white head but not the majority of them. They aren't painful just itchy. I have no other symptoms just irritable from being so freaking itchy! I was in the ocean on Friday and by the end of the day Sat I was covered. Could this be sea lice, even with its prolonged reaction?
