Surely playing through pain in his current condition is foolish? Even if the doc sees no problem, surely pain is an indicator to stop?
I agree, and he should certainly consult different people (and probably has) before considering playing with pain.
That said, i myself has pain in joints that actually got better and disappeared once I trained thru the pain. So there can be situation where it may be okay to got thru a temporary phase of pain, i doubt thats the case here though
