Actually in my observations the scabies are actually raised bumps primarily and once you hit post scabies the bumps gradually flatten out and fade away, with the exception that sometimes your skin mite produce more raised bumps from infection or hair follicle problems. So typically it is kinda hard to say.

Raised bumps maybe could pertain to you have a more severe case of scabies? Are the bumps secluded to a certain area of your body? Are you seeing groups of lessions rather than just one here and there? My guess is maybe you just irritated some areas of the skin that were infected and maybe given yourself a secondary skin infection. This is typical with post scabies as the skin is in very bad shape from the treatments and the damage the scabies mite did under your skin. Try using sulfur creams on those areas and they should quickly get better and this will prevent it from spreading to other areas also.
