I think I finally crashed from exhaustion. As I was leaving a store I suddenly felt achey all over and disoriented. Went straight to the apartment and went to bed. Within 30 minutes I had a 101 degree fever and severe chills. PA called up the doctor and got a flu prescription. By the time he was back the fever was falling. Within about 5 hours I was still achey, but felt much better. I'll continue the flu med, just in case.
