influenza
"Flu came out of nowhere on a Saturday. Chills and headache were the worst but also had cough, earache, body aches. Temp was 102. Spent the weekend in bed, not sure I would survive. Went to DR. on Monday and tested positive for flu. Started Tamiflu and a Z-pak. By Tuesday I was feeling much better. Expensive but I do not regret the cost because it worked and I only had to pay copay.  Many years since I had the flu and was much worse than I could imagine. Would pay whole $80 if needed."
