influenza
"Came down with the flu on Sunday had fever, back ache, sore throat, etc went to the doctor but they didn't check for the flu said it was sinus infection. By Tuesday I was still feeling ill so went back to doctor and had positive flu test. Started tamiflu that day. Tamiflu caused me to be extremely nausea on Wednesday I was throwing up from Tamiflu. I did not throw up or have diarrhea in the 3 days I had the flu. Not sure if I want to keep taking it or not but it's Thursday and although no fever or back ache still have flu headache and exhaustion."
