Sick of your chest mimicking a percussion band due to costochondritis? Your savior just might come wearing a physical therapist's uniform and a whit of undeniable sass - your sternum's knight in shining armour.

Now, let's make it clear: costochondritis is a troublesome, yet self-destructive troll camping in your chest cavity fueled by deplorable posture and reduced trunk agility. Heightening your strength and flexibility through physical therapy has the power not only to shove this troll back under its bridge but also to padlock the entrance.

Your physical therapist, fresh from scrutinizing your medical history and conducting eccentric-sounding tests, will quest after the origin of your costochondritis. With the cause laid bare, cue the battle plan conversation and a forecast of your journey to painless breathing and unrestricted movements.

Your role? Active participation in the therapy magic. You'll be sent on a mission with carefully selected exercises to restore the agility of your ribcage and chest domain - designed for your comfort and well-being, not as some medieval torture methods.

But hear this: if any exercise enkindles prolonged chest or rib pain, halt! Consult your therapy wizards for they can modify the exercise's intensity.

A crucial aspect of physical therapy and warding off costochondritis recurring like a bad sitcom, is maintaining a regime of strategic stretches, focused breathing, and posture-improving workouts.

Typically, the lifespan of costochondritis is pretty short –like a mayfly's lifespan in relative terms. But the physical therapy can expedite the healing process.

As a rule of thumb, for a period of four to six weeks, expect to engage in one or two physical therapy sessions per week. However, don't be surprised if the timeline varies depending on the severity of your condition.

Moreover, a prolonged affliction – think more than six weeks – may warrant a discussion with your healthcare provider. Occasionally, a stronger anti-inflammation regimen, such as steroid injections, may be necessary.

In summary, while costochondritis can feel like a year-long music festival in your chest, physical therapy is a potent conductor that can silence this relentless beat.
