Suggest treatment for scabies

Question: Hi I have been to five doctors with scabies symptoms and no one seems to believe it is scabies. Samples were taken from one large sore I have on my knee and tested for fungus which came back negative, but no microscopic tests. I have itchy red sores that look like they have feint brown tracks that come out of them that loop around my arms and legs. Some zig zag. I also feel the pin prick bite and a crawly feeling all over. I also saw black specks come out of one of the sores, that started with a very white film. When the white crusty film went away, the black specks appeared. This happened after I used some scabies cream (I convinced an Urgent care to give me the cream, though they also didn't think it was scabies.) If it isn't scabies, what can it be?? I also feel itchy in my nose, eyes and ears so I think these things are spreading.

I sent pics. This is the main sore. It started with a crusty oozy patch that grew in size. The crusty stuff went away and now it's more of a purple thickened patch. The elongated sore next to it is where I saw the white flaky stuff and then the black specks. Those are gone now. The sore remains. The little red sores pop up after feeling a prick sting which tells me it is some sort of bug. It itches and bleeds and white flaky crust drops off of it. Doctors are confused why no one else in my family has gotten it, including my husband. The sores were confined mainly to my legs but have spread to my arms and now my back and front and my neck. My ears are also itchy. I've read on the internet of folks having scabies on their faces as well as in their noses, maybe it is not likely but not impossible either. Something I just thought of, about five years ago, one of my blood tests came back high in the IGM protein and they told me that a high reading in that protein suggests a parasitic cause. They did not pursue this but I am wondering if this is connected to that in some way. I am unemployed at the moment but got symptoms while visiting relatives in Kentucky around the end of XXXXXXX Ooops missed two of your questions. I feel the crawly feeling mostly at night, but that could be because I'm not distracted. I do feel the itchy bitey and crawlies during the day as well. The sores aren't fluid filled, they just start as an itchy bump, I scratch it and a small white flake of skin comes off leaving a hole that bleeds. Once it bleeds it scabs over and it still very itchy. A light brown track comes out of the red sore. The doctor I saw this morning said that she didn't see the tracks. They are very hard to see but I know they are there, I can see them looping around my in little curly cues. Why she couldn't see them I don't know.
