Yes there are tiny microscopic bugs that can live under your skin and lay eggs under the skin.
The tiny bugs that can live under your skin are scabies.
The scabies are tiny microscopic bugs that can only be seen under a microscope.
The scabies burrow underneath your skin and feed and lay eggs.
Scabies are very small bugs and are very good at hiding so they are impossible to actually see unless you use a microscope to see the scabies.
Scabies are microscopic parasites that are also called human itch mites.
To get rid of scabies you need to see your doctor and get a prescription medicine that is in cream form that kills the scabies and itch mites.
Home remedies can help such as applying apple cider vinegar which can kill some of the itch mites but the only real cure is to use a prescription cream.
