I've had hives on and off since Saturday night, and I've run out of ideas of what it could be. I went to the doctor and revived a shot, and they're still coming back. They usually happen in the evening and early in the morning, but are clear from around 9-4 during the day. Right now it's 1:30 and I'm covered in hives, no trouble breathing or anything, but just wondering if anyone else has experienced or seen anything like this, or has any idea of what it could be? I have an appointment to run an allergy screen, but it just seems unusual for an allergic reaction. Any help is appreciated
