I get all over body itching every night. I have no rash but red hives erupt(in a scratch pattern) where I scratch. I will itch for about 30 minutes then it will go away and the hives will go away, too. Then I might get it in another spot later. It can occur anywhere, my feet, my head, my legs, my hands, my elbows, anywhere! Benedryl helps but I'm tired of having to take it every day. I have had this for over a year. During the day I have no symptoms at all-no itching and no hives.
