Itching and rashes are symptoms that seem to go together. However, it is possible to experience itchy skin without having a visible rash or any noticeable skin changes. The causes of skin itching, or pruritis, are usually harmless. They are often linked with temporary issues, such as dry skin or a bug bite. Less commonly, problems with the nerves, kidneys, thyroid, or liver can cause itching sensations without necessarily causing a rash. Depending on the cause, a person may experience an itching sensation all over their body or in one specific area. The itching can vary from mild to extreme. If a person is concerned about unexplained itching, extreme itching, or itching that lasts a long time, they should see their doctor to determine the cause and get advice about treatments.
Photo taken in Loei, ThailandDry skin, or xerosis, is a very common complaint. The skin can start to feel itchy when it loses moisture. Dry skin can present as flaky or scaly. It is common among older adults, especially during the colder months. The following tips can help relieve dry skin and prevent it from drying out further: Avoid using soaps with harsh chemicals, as these can dry out the skin. Instead, try to use hypoallergenic and fragrance free soaps and skin care products. Use a humidifier at home to add moisture to the air. This helps prevent winter related dry skin. Apply moisturizer regularly, especially after getting out of the shower or bath. Vaseline or heavy creams such as Vanicream or Cerave are popular options. Avoid taking showers that are longer than 10 minutes. Also, keep the water lukewarm rather than hot. Do not bathe multiple times per day. Avoid scratching dry skin, as this can damage the skin’s surface. If the skin breaks, a person is more likely to experience scarring and infection.
Mosquito, spider, and other bug bites can make skin around the bite feel itchy and irritated. Bug bites can leave behind a very small hole or pinprick-like area. However, they can be so small that a person may experiencing itching but not see the actual bites. Many bugs can bite a person — including bed bugs, mosquitoes, and lice — and the treatments can vary depending on the type of bug that caused the bite. If a person experiences continued itching after a bug bite or bites, they should see their doctor. Avoid scratching the area, as this can make the itching worse. Also, do not use over-the-counter topical antibiotics such as Neosporin, as some people can develop an allergic reaction on their skin.
