1. Unfortunately there really is no consensus here or anywhere on which treatment is the best, but as far as pure studies and science goes I would list them to be about like this,
Pentox, Cialis (and OR Arginine/Citrulline), CoQ10, ALCAR, and I would put
VED and
Traction very close together, but
traction helped me more. Here is a study on
traction in during the
acute phase.
Acute phase Peyronie's disease management with traction device: a n... - PubMed - NCBI2. This is a controversial topic but the basic idea is that erections are good for the penis, just not to the point where you're aggravating any injury, vasculature, or lymphatic vessels. I cut down to around once a week and that helped me greatly. Since you are 27 having erections shouldn't be an issue for you. The reason why you hear "use it or lose it", is because many people much older than you struggle to use it at all. In your position you should focus strictly on minimizing damage, and if you masturbate or have sex, be very careful. I once read somewhere that
inflammation can stay trapped in the penis for months. Where that information came from and what it means, I don't know. Avoid masturbation binges at all costs, be realistic about how often you masturbate. Keep a log and be willing to truly cut down. Keep in mind that penile injuries take a long time to heal, and there is no standard here. It may take much much longer, and even then never truly "heal" right.
3. If it hurts, don't use it, would be my basic logic here. I think most people would agree with me on this, but again, it's hard to say.
The ridges are likely to be veins which originated from your injury. Penile injury is rough on the blood vessels and arteries of the penis, and some people even think that this is where Peyronie's originates from. Regardless of the truth of the matter, you should not be too worried and do your best to focus on healing. I hate to be the bearer of bad news but there are very little knowns about penile injury and Peyronie's. No one case is the same, and to what degree healing is even possible, I don't know anyone who knows.
The good news is that you are likely to feel better and have improvement over time, how much time, we don't know!
