PJFT tomorrow and do you know what i' e done? I've strained an intercostal muscle in my chest, right next to my sternum behind my left pec. So now I get a slight-moderate pain when I inhale. And I did it last night while foam rolling. No way i'm phoning up my RO to tell him I can't do the run. I'm not confident about passing first time anyway, but just added to the difficulty. Its going to be hell and i'm guessing i'm going to have to constsntly remind myself i'm not having a cardiac arrest.
