A year ago, I was going on a trip to South America, and one of the vaccines they gave me a few days before I left was for H1N1. Well, about a week after I got the vaccination, I got what I think might be the flu. I was suddenly hit with a fever of 102 which lasted for about 5 or 6 days, headache, stuffy nose... but those were the only symptoms for he first few days. After a few days, I started feeling junk in my lungs, but I wasn't really coughing. But within 4 or 5 days, I was coughing up so much mucous. I've never had a cough that bad that produced to much mucous in my life. I had that cough for over two weeks. It was awful. I often wonder if the Swine Flu vaccination actually gave me the flu... does this ever happen?
