4. Signs and symptoms of scabies include:
• Itching, mainly at night: Itching is the most common symptom. The itch can be so
intense that it keeps a person awake at night.
• Rash: Many people get the scabies rash. This rash causes little bumps that often
form a line. The bumps can look like hives, tiny bites, knots under the skin, or
pimples. Some people develop scaly patches that look like eczema.
• Sores: Scratching the itchy rash can cause sores. An infection can develop in the
sores.
• Thick crusts on the skin: Crusts form when a person develops a severe type of
scabies called crusted scabies. Another name for crusted scabies is Norwegian
scabies. With so many mites burrowing in the skin, the rash and itch become severe.
