Hello I have had hives for about 2 weeks now and don’t know why they came, I can’t think of anything different that I’ve eaten or used. My son has a new puppy at his house so we are thinking all sorts. I’ve had swelling of my eyelids one then the other then part of my lip and then my top lip. The hives seem to come during the night and then calm down during the day..I’m wondering how long this will last as it is awful and never experienced anything like it before. Thanks
