In Oct 07 my son contracted scabies. We were given meds for it for everyone in house to use, I cleaned everything, washed everything I mean everything. The scabies went away. Question is, now I notice he has tiny tiny little bumps on his arms, itchy. Can scabies return after 5 months??? Im hoping its just a rash of some sort he has been playing out side alot. But I notice I have little red bumps on my arm too. any insight here?
