Grade: 3
Bleh, first flu in a long time (I think ... I have a bad memory). Sunday afternoon, thought the aches were from Saturday's moderate effort, but no. Throat, fever (1-2°F), and the worst was a series of left-side muscle spasms in my upper-to-middle back, and left shoulder. Sunday night, in bed.
I / A every two hours and massive salty/sugary hydration for the win!
