RM - Pleurisy is something that does not like to be irritated by deep breathing. Imagine that inflammed tissue around your lung and everytime you breath in deeply it's getting rubbed and irritated more. Honestly, I would not do anything strenuous cardio-wise until you can take a nice, super deep breath without pain. And then I'd still wait at least one more day.
Take care.
