I have red bumps break on my body, a few everyday, itchy, it gets bigger when I scratch it. arm, waistline, back, chest, one or a few at a time. It started about two month ago, stopped about 2 weeks, and come again. It looks like flea bite, but I haven t see any in my bedroom. And a lot of times it starts itchy but nothing can be seen, after scratching, it gets bigger and then look like flea bites. I have a dog who got flea but treated 2 month ago. I have washed bedding, did everything. We have hardwood floor with a couple of rugs.
