Breaking out in hives

For the last three days I have been breaking out in hives. I was wondering if anyone else had this experience. Or has anyone's allergies changed after surgery.

Are you taking the B-12 injection??? Are the bumps on your forehead and cheeks?? if so u may be having a reaction to too much B-12 in your body! I had the severe acne-like bumps for the injection.

I am taking a liquid form of B12 that you leave under your toungue for 20 seconds once a week. The hives seem to move everywhere; arms, legs, stomach, face. I have been taking Benedryl but it makes me tired and dragging around. MY PCP gave me some pills methopredesone but it did not seem to help. Maybe I will skip a dose of B-12 to see if that helps. Thanks for your input.
