Wondering if anyone else has experienced this. I was sleeved on May 6th, 2014. I advanced to puréed foods yesterday & am finally able to meet my Protein & Water goals. I went to my bariatric center 5 days ago for a checkup- they gave me an injection of Thiamine and another of B12.

I started with 2 small hives 2 days ago on my abdomen, which advanced to my chest. Yesterday the hives spread to my groin & legs. I took oral Benadryl as instructed, which gave me some relief. I woke up at 2 am this morning very short of breath, went to get a drink from the bathroom & saw that the hives were around both eyes & on the eye lids. Went straight to the Emergency room- the physician suspects a reaction to the Thiamine injection. I've been admitted to the observation floor, on IV steroids, Benadryl, and Pepcid. I can't think of anything new that I've added food wise, no new detergents, etc., so I'm thinking it must have been the B Vitamin shots.

I am allergic to Ursodial. Took a few days after surgery for that to creep up and the hives to come out. Apparently many people are allergic to that stuff (according to my doctor).

I hope you feel better soon!

Yikes! I haven't been taking that yet- I have it ready to go, but the surgeon told me to hold off until he sees me. My appt is today, looks like it may be delayed a day or two.

The B12 is important. Perhaps when you feel better you can take one liquid dose rather than a shot and see how you react.

I know how you feel though. I would be scared to death if I had to go to the emergency room for hives.
