influenza
"Symptoms started Sunday eve. Felt lousy Monday. Achey. Sweaty. Feverish. Went to doc Tuesday bc I was sure of having strep (strange rash) but was diagnosed with flu. Started tamiflu at noon Tuesday. Wednesday 7pm, I sound like hell, coughing hurts, but I can actually walk about. Hoping for a night without having to change my sweaty night clothes. I was leery but feel lucky to have been diagnosed in time. Last time I had the flu a few years back, I was flat out for a week. Little stomach upset (diarrhea), but very mild and worth it"
