For persistent or severe itching, see your health care provider for a diagnosis and treatment instructions.

In the meantime, you can take some steps to help deal with the itch:

• Avoid scratching or rubbing the itchy areas. Keep fingernails short to avoid damaging the skin from scratching. Family members or friends may be able to help by calling attention to your scratching.
• Wear cool, light, loose bedclothes. Avoid wearing rough clothing, particularly wool, over an itchy area.
• Take lukewarm baths using little soap and rinsing thoroughly. Try a skin-soothing oatmeal or cornstarch bath.
• Apply a soothing lotion after bathing to soften and cool the skin.
• Use moisturizer on the skin, particularly in the dry winter months. Dry skin is a common cause of itching.
• Apply cold compresses to an itchy area.
• Avoid prolonged exposure to excessive heat and humidity.
• Take part in activities that distract from the itching during the day and make you tired enough to sleep at night.
• Try over-the-counter oral antihistamines such as diphenhydramine (Benadryl), but be aware of possible side effects such as drowsiness.
• Try over-the-counter hydrocortisone cream on itchy areas.

Call your provider if itching:

• Occurs with other, unexplained symptoms
• Is severe
• Does not go away
• Cannot be easily explained

Most itching does not require medical evaluation. Look for an obvious cause of itching at home.

It is sometimes easy for a parent to find the cause of a child's itching. Looking closely at the skin will help you identify any bites, stings, rashes, dry skin, or irritation. Often the cause of itching is fairly obvious, such as a mosquito bite.

Have the itching checked out as soon as possible if it keeps returning and does not have an obvious cause, you have total body itching, or you have hives that keep returning. Unexplained itching may be a symptom of a disease that could be serious.

Your health care provider will take your medical history and do a physical examination.
