I used to get hives very frequently, about twice to four times a year, but I haven't had them in around two years. Six days ago, I woke up with the red, raised bumps on my hands. I thought it was nothing, because all the cases I've had in the past had gone away within 24hrs. This time, it was different. Today is the evening of the sixth day and the hives have not gotten better, or gone down. I've been taking Zyrtec and Benadryl which helps the symptoms, but the hives keep coming back after 4-8 hours. I haven't felt any closing or tightness in my throat (as I never have,) but I'm afraid that might happen soon. I've been to an allergist twice and all results came back negative. I haven't used any new skin or hair products, and haven't eaten anything unusual, either. My doctor said she couldn't do anything about it, and just to keep taking the antihistamines. I'm really stumped (and stressed) about what to do right now. Any input helps!
