Symptoms of itchy rash
A rash or itching is a common skin symptom and often leads to scratching. Patients with itching may or may not have a skin rash. The itching may happen on only some parts of the body or over the body and may have a negative effect on the patient's quality of life, such as causing distraction, interfering with work or sleeping or negatively impacting mental health.
