Visual symptoms of scabies: what do they look like, and where are they found? Scabies can be on almost any part of the body, but often the hands are the first area affected. Scabies also particularly like to live in skin folds and crevices, such as those on the inside of the wrist.
The most common scabies symptom is a skin rash with small red bumps and blisters that only affect specific areas of the body. The itch mites actually feed on dissolved tissues, not blood, and the most common areas of distribution are the finger webs, wrists, underarms, abdomen, buttocks and groin.
