I haven t eaten pork for many years and after consuming some on Friday I started having abdominal cramping, sever gas and diarrhea. This has gone one ever since, but I also have other odd symptoms. I had a rash on my stomach, chest and back, which has since cleared, and I also have a headache & earaches and tight feeling muscles in my upper back/neck. My sinuses also seem to be clogged. I am wondering if it could be a negative reaction to eating the pork, or if it s some kind of virus, and if I should see my doctor.
