Yesterday and today my belly and chest are covered in hives.  i had them during the day yesterday, they lessened at night, now they are back with a rage.  Has anyone experienced this?  What can I take for it?  or is it just topical stuff?  My Dr. doesn't open for another hour, I plan to call, but I'm hoping for some relief asap.                
                             
        
Re: Hives
My OB said I can take Bendryl which is what I would take for hives.
Start wracking your brain for anything you've been doing/eating differently lately. GL!

I had HORRIBLE hives at 9 weeks - covered from head to toe - and we still have no idea what caused it. They lasted about 5 or 6 days and my OB told me to take Benedryl as needed. In addition to that, I used hydrocortizone (that spelling could be totally off, sorry) creams and the topical Benedryl spray. I also took like-warm baking soda baths that gave me some immediate/temporary relief. Beware not to take a hot bath or shower though, as that can lead to flare-ups (not to mention we shouldn't take hot baths while pregnant anyway).
I feel your pain, it is horrible. I hope they clear up soon, but until then give yourself some relief. Good luck!
