Mysterious ailments plague me

All of a sudden, I notice sharp pains in my lower shins and the back of my knees. Normally, I'd be as psycho about this as the next runner, but I understand what is going on here. It's the usual tapering mystery pains that I always get. There is a theory that once the workouts are decreased or eliminated prior to a race, the body heals itself and the pains are the areas where the muscles are regenerating. Do I believe this and think that it's not a real injury? You Bet! I have to in order to not psych myself out for tomorrows race. If not, I'd be a basket case.
