Hello, my husband and I are both having nausea, frequent bowel movements, stomach pain, belching, he is vomiting and I am having bad headaches. We both had flu shots. He is 56 and I am 55. He also has celiac disease and I have IBS. It s just odd for us to both be sick at the same time. We haven t had any diet violations-everything we eat is made at home. He did eat breakfast today and I have had some chicken broth. But he is getting violently ill.
