Yeah I tried doing the scabies ink test but could not tell if the ink was above or under the skin. I bought a pocket microscope online for about 15$. Here is the website I got it from and they also have some scabies creams and soaps.
Pocket Microscope for ScabiesThey are advertissed on the banners on the site as well.
I had scabies mites but some people just start treating without knowing what kind of mite they are dealing with.
