After I sustained a long-term injury, much like the original poster, my urologist told me there’s nothing to fix these sort of things. I knew it and he knew it. The only thing that can help is the drugs he prescribes which can assist in healing it. If it wasn’t for me taking viagra/l-arginine before bed, I would probably still be in my injured state. Because if you aren’t taking the measures needed to heal it, it’s not going to heal itself sitting in that firm-limp state it’s in; trust me, I’ve waited 10 months to no avail. Heat wraps and a PDE-5 inhibitor before bed, or substitute that with l-arginine, and you should see some improvement after a short time.
Also interested in what improvement you’ve seen daysdrag.
