Dave, hello and welcome. AS you probably know, it can take up to 3 years or even never for function to return. You don't say wheter you had nerve sparing surgery, but reading your stats, I'm guessing you did and the nerves are intact but still regenerating and healing. I am only 3 months behind and also have no response to anything but trimix. My procedure is 50mg generic Viagra nightly, with 2000 mg of L-Arginine, and daily use of a vacuum pump mornings. I inject with trimix twice weekly, most weeks. The only thing I can tell you is to continue exercising those blood vessels and nerves and hopefully nature will take its course in healing and reconnecting things for you (and me). The Pyronnes is a sad fact and result of the injections, most likely, and can be treated easily. Consult with your doctor as to whether you should continue the injections while being treated.
