A common skin condition, scabies causes intense itching. It is easily caught through physical, skin-to-skin contact with people who already have the condition. Scabies is caused by mites burrowing under the surface of your skin.
Visit the doctor. The doctor will usually only need to see the rash to diagnose the condition but might also take a sample by scraping under the bumps and looking for the presence of mites, eggs, and feces under the microscope. Be sure to tell your doctor if you are pregnant or have any problems such as serious illness, or other severe skin diseases.
