7. Aches and pains
If you have contracted food poisoning, don’t be surprised if you start to feel aches and pains in your muscles. This is just another sign that your body is working hard to rid itself of the invading bacterium. Muscle aches and pains can also be the result of dehydration.
Vomiting, diarrhea, and fever all deplete fluid levels, which means your muscles won’t have access to the fluids that they need. Increasing your fluid intake could help with this symptom, as could over-the-counter pain relievers.
