Can physical therapy help my heel pain?

Absolutely.  Physical therapy helps to decrease the inflammation in the area and strengthen the foot.  It is more than just stretching.  A good therapist will give you a good amount of hands on treatment. Heel pain can be treated through modalities, ultrasound, electrical stimulation, iontophoresis, manual therapy, and therapeutic exercise. Each of these will be focused on decreasing pain and inflammation.  Your therapist will provide appropriate interventions including flexibility and strengthening exercises.
