Pork Tamales. I ate about 6 in a three day span. I had fever, nausea, vomiting, causing me to have low blood sugar from the food poisoning and unable to eat. This was a few days ago. I ended up in ER. I’ve been battling this fever and nausea and diarrhea for three days now. I also will be taken back to my home town for a month so that my family can watch me. Today I had nausea and abdominal cramping but I do feel like it's slowly getting better.
