Healing just IS. Your body already has shown you how you will heal and over what period of time. If some of the procedure is the removal of scar tissue, you will find pain associated with it; however, as one who also creates scar tissue at break neck speed [you know? In view of my recent cervical fusion, that saying takes on a new meaning.] I personally know removal of scar tissue doesn't produce much in the way of discomfort discernible from the surgical intervention itself.
