"I have itching on my arm during the summer?"

It is possible that the itching on your arm during the summer is due to dry skin. I recommend using a fragrance-free moisturizing cream like Aveeno as often as needed, especially when the urge to scratch arises. You should also use a fragrance-free soap like Dove, and after bathing, avoid rubbing your skin dry. Instead, gently pat your skin to leave a thin layer of moisture and apply moisturizer within 5 minutes of showering. Try these measures for at least 1 week and see if they help alleviate the itching. If you have any other questions, feel free to ask.
