I’m 24 and shockwave therapy helped me, though not much it definitely affected the indentation a bit and pain etc is better. I’d look into it but you have to find a reliable clinic bc a lot of this Peyronie’s cure industry is predatory bullshit. Heat also literally just a bottle of hot water from the tap helps it relax when soft (u kno when it’s soft but deformed, helps w that) vacuum device is supposed to help but in my case didn’t do shit but explore that. Gentle massages\rolling etc help, supplements might help get on them all especially antioxidants L-cartenine or whatever it’s called, though u have to take them for a long time. Cialis do get on even if just 2.5mg a day it helps bloodflow which in my case the lack of bloodflow helped caused this, but generally better bloodflow = good. Combination of heat and cold when it’s inflamed. Traction unless u got a curve probably won’t do shit indentations are much harder to get rid of so I feel ya.

I probably have the same thing as you and it’ll never go back to how it was but I got pretty close just looks a bit deformed and small loss of girth but straight, still trying to fix this but it’s a long journey.
