Sudden development of itchy rash on the arms. Medication?
Last night I developed a rash on my arms for a couple of hours. It soon went away. This morning I developed a rash on my stomach and back, and a small amount on my arms. After appliing caladryl to the areas. they stopped itching. Mya rms have cleared up but the rash is still visible on my stomach no itching at this time.
