McDonald's review: McDonald's food

In March 2023 I went to a McDonald's in 29 palms California. I ordered a mcdouble and happy meal. I noticed that the mcdouble had a lot of ketchup in it but since I like ketchup I ate the sandwich. My wife said she didn't want the happy meal so I eat that to. About 2 hours later I was throwing up badly. I felt incredibly bad and stomach was in knots. My head felt like a balloon and head ache was bad. I called the McDonald's and reported to them what happened. The seemed to busy to care but said they would inform there manager. After a couple days I went to the hospital for care, food poisoning. I called back again I talked to the manager who referred me to there insurance company. There insurance said did you get a stool sample.? I said no I just did what the hospital wanted me to do... There insurance denied my claim right there. It's baloney as my hospital said I had food poisoning. McDonald's representative seemed not to care either about my getting sick. I am looking for an attorney to help. Thank you
