I understand the addiction to exercise...but remember that addictions keep us from being objective and rational. If you think it's hard to cut back on your running, how happy will you be if you can't run at all, or even walk? Maybe practising some wise prevention now for a few months you'll remain a runner the rest of your life. Do you really understand what it means to 'learn the hard way'? Have you read the stories on this board of those of us who not only can't run anymore we lost our jobs because we couldn't walk or stand?
I'm sorry to sound so dark...but ignoring the pain can (not always) lead to drastic and tragic results. And so far, no one can tell who will and who won't be disable by pf when the 'little pain' starts.
