On Sunday, I got the nasal spray vaccination for swine flu. I already had gotten the seasonal flu shot. Starting on Friday, I began having what I believe are flu symptoms; coughing, stuffy nose, aches and pain in my back, headaches, sensitivity to light, I feel like I have a fever (I can't find my thermometer), and I am constantly cold.
You probuly got the swine flu since they put some of the swine flu bacteria into your body that could happen with any nasal spray it may just be a light case tho go to your doctor to find out
I've had no symptoms since I had my H!N! shot last Monday. this is Saturday. My son who works at a clinic told me that people who are coming down with the flu, already, get very sick from the shot or spray.
Yeah i had most of those symptoms too a couple of days ago. it may or may not be the swine or H1n1 (whatever you prefer to call it) however, since you got the vaccine if you do happent to have swine you will have a mild (not bad) case of it. Do not worry if you have it just take a few days off to get better. 
Hope I helped!
