Itching, that annoying, sometimes persistent problem can actually be a very complicated symptom. When accompanied by a rash, the problem is usually a bit easier to diagnose but itching without a rash can be more difficult.
Dry skin, especially in fall and winter, is generally the most common cause of itching, followed by a number of medications.
Some underlying diseases such as thyroid, kidney or liver disease, anemia, diabetes, cancer, certain nerve conditions, and some mental health conditions can be an underlying cause of itching.
Your dermatologist can evaluate you to determine the cause of your itching and offer suggestions for relief.
