Do I have a claim against Sunoco and Meijers for serving contaminated food causing poisoning, even though, I did not get medical attention?

About a month or two ago, I bought an egg salad sandwich from a Sunoco Gas Station here in Michigan. About two days later, I became violently ill feeling as if I was going to die. I experience stomach cramps, sweats, chills, and watery diarrhea. After the diarrhea, I felt better and felt I didn’t need emergency medical attention, given that, I don’t have health care. That day I had eaten two cloves of garlic when I usually eat only one and thought my illness came from the garlic. However, two weeks ago, I went to Meijers and bought a fried chicken breast and while eating it, I discovered pink flesh and pink juices. I immediately went back to the store and showed the manager who offered a refund. However, Meijers did not throw out the rest of the chicken and continue to sell it. A couple of days later, I began having dizzy spells and had a bloody stool two days later. I went online to search Salmonella symptoms and discovered it was the egg salad sandwich that got me ill the first time, therefore, I called Sunoco and the manager said I was too late to make a claim. I told him had I known that it was the egg sandwich instead of the garlic that got me ill, I would have immediately contacted him. I know medical expenses incurred from being sick are one component of how much I could recover. My pain, suffering, and illness are another component.
