Hi, for about two weeks I have noticed what were first small pimple like bumps appear on my arms and legs. They were quite itchy but after about a week they were gone. A few days ago bigger bumps appeared, they look like bug bites and are quite itchy. My sister noticed the same thing happening to her. I'm concerned, what might this be? My doctor simply looked at the bumps and declared I have scabies, however no tests were done and I would like a second opinion, as my parents who also live with me have no such bumps appearing on their skin.
