Burning and itchy skin with no rash can have a variety of causes including dry skin, internal diseases and nerve disorders, according to Mayo Clinic. Treating the condition involves diagnosis and using various itch-relief methods.
Dry skin is commonly caused by winter weather, steamy showers and moisture-robbing soaps, notes WebMD. Dry skin during winter weather is due to low humidity in the air and can be treated by installing a humidifier in the home to keep air moist. Steamy showers can dry out the natural oils in the skin more quickly, so it is best to keep showers short and make the water lukewarm. A mild, fragrance-free soap that moisturizes and is specially formulated for dry skin can help this condition as well.
Internal diseases such as liver disease can also cause itchy skin, explains Mayo Clinic. Typically with internal diseases, the whole body itches and the skin itself looks normal. In addition to itching, liver disease is often accompanied by symptoms such as weakness and fatigue, weight loss, nausea, vomiting, and yellow discoloration of the skin, states MedicineNet.
Nerve disorders such as diabetes mellitus can contribute to itchy skin, notes MedlinePlus. The most common type of this disorder is Type 2 diabetes and symptoms include being very thirsty, urinating often, feeling very hungry or tired, and having blurry eyesight. A blood test can diagnose this condition.
