In the absence of a genetic predisposition for the malady,
DD/DC, injuries would result in repairs not proliferation.
A possible analagous situation would be high blood pressure
and salt; a relationship may exist, but salt does not cause
high blood pessure (it may not even contribute to it.)
Prevailing thought: one has DD/DC and is unaware until X
happens and the condition is manifested. If one never had
an injury. the DD might have been a "lump" explained away
as "holding a briefcase" or "using a tool," or, a "callous."
It is a genetic condition that effects conective tissue
in the palmar aponeurosis, plantar neurosis and the penile
erectile tissue (Peyronnie's disease.) To date, no known
cure exists; treatments are available. We are all learning
together. Recently, Allopurinol has been mentioned as a related gout medication. Until the genome revals a genetic
origen and remedy, we can only treat symptoms. Good luck.
