Saw doctor Wednesday, had a tentative diagnosis of pneumonia, prescribed antibiotics and told to stay off work until Monday. Recovery in progress. Still short-winded and rather lacking in endurance, but I can get some light stuff done. Managed to catch up with laundry yesterday. Later today (Sunday) I have to get to the grocery store; a trip was already overdue when I got sick a week ago, and we've run out of even more items since then. The grocery trip should let me know how difficult going back to work will be. (It's not a strenuous job, it's just pretty continuous.) Workplace requires FMLA paperwork to authorize a return to work if someone's off more than three days, so I'll probably have to have a follow-up appointment with the doctor.
Everyone else in the house has come down with the crud, too, to greater or lesser extents. While speculation as to who infected who may be entertaining, I've decided that "I Blame Society" is the best response.
Considering how many people in the household got sick so quickly, I found myself wondering if it wouldn't be suitable to hire someone with a horse and wagon to drive up and down the street outside, shouting "Bring out your dead! Bring out your dead!" (I must be getting better; my sense of humor is getting sicker.) (i.e., normal)
Later: Grocery trip went fine, came home a little tired but not badly. I should be okay going back to work in the next few days.
