On new years eve and new years day, I ate pork with my family. I doubt it was undercooked and my other family members haven t been sick like I have. On Jan 2 I had instense headaches. On the 3rd I started having pretty bad stomach pain and constipation. On the 4th I felt okay so I didn t eat until bed time and when I did I had stomach pain. Today I have body aches, stomache pain, diarrhea, itchy skin, and body aches. I m not sure to treat it like the stomach flu or go to the hospital because of a parasite from the pork.
