I read in the survival guide that if scar tissue forms in an injured area, it is not Peyronie's. It is Peyronie's only when scar tissue forms in healthy tissue. But aren't injuries or traumas possible causes of Peyronie's? I didn't get this defition. I have a little string of scar tissue due to a trauma, the penis even got swollen, so I don't have it? What is it then? Can it go away?
