What Causes Hives Along With Vomiting And Nausea?

i woke up 3 days ago with red hives on my facial cheeks, they were not raised but appeared under the skin, then as the day went by i had hives in the center of my neck, that were raised. Now my face is clear, but the hives are still on my neck and i now have a rash/hives on upper chest. This area is becoming itchy/burning. I also have been experiencing nausea without vomiting, thru out the day which each episode last for 1-2 minutes and is very distressing. the nausea was present for about 1-week prior to hives/rash? no new cleaners or lotion, makeup. went thru a whole checklist. I have been taking probiotics (phillips) for 90 days could this be the culprit?
