better train while not training

Saved a ball with the left side of my ribcage.
Now can't sleep on my left, can't breathe normally.
Plus i've got a very bad sore throat, not sure from what.

Just saw doc this morning, said it's a muscle overstrain, no polo for at least a week.
Gave me medicine for pains, now i'm drowsy, can't read my health psychology text with full focus.
Got a test this sat and next thurs, and I'm barely halfway through my 'Issues of Developmental Psych' essay assignment.

sigh. Am I stressed?
