Itchy: Do you have dry skin? This is one cause. Occasionally itchiness develops at night when the body temperature rises. You can prevent this by taking benadryl( may make you drowsy) or Claritin (loratadine). Overactive thyroid or polycythemia(excess red blood cells) are rarer causes. Your physician can evaluate you and order any appropriate tests.
