My DS11 had a bout of it two weeks ago. He started with a low grade fever on a Tuesday night, with a stomach ache and headache. The fever got a little higher the next morning, and the other symptoms were still present. After taking a nap in the afternoon, he spiked a 104.2 fever, so I took him to the ped who diagnosed H1N1 after testing. He also said he had a little trouble breathing. (She said she couldn't officially call it that because the CDC requires the testing be done in a hospital to officially say it's swine flue. But she said that was what it was.) So she gave us a script for Tamiflu, which had to be compounded because there was no liquid at any of the pharmacies. DS took one dose and immediately threw it up because it tasted so awful-maybe because of the way it was made. So...we settled for Tylenol and Motrin to keep the fever at bay. The symptoms stuck around until Sunday, when he felt much better.
So symptoms were: High fever, loss of appetite, headache, tummy ache, difficulty breathing, and lethargy. for 5 days.
I hope everyone feels better soon.
