Peyronie’s disease - plaque on penis / maybe from injections...

Hello all. I am 1 year and 2 months out from having my prostate removed from Cancer. I am doing well. PSA is not detectable - bladder doing really well - little or no dribbling. I have just been diagnosed with Peyronie's Disease! This is plaque that builds up on the penis. PA said it could be caused by the injections for erections??? No cure - no treatment. I was told it would go away on its own?? Anyone else heard of this - or had this?
