seems like you are doing very well as Dan said before , it does take time to heal and slow slowwww progress when it comes to your nerves, but if you so fas back to 60-70% you are well on the right path, i left injections as m last resort , i a almost a year post op from my
open RP, and my progress is very slow but there is a noticeable progress, i am back to almost 90% wit meds and 100% with th pump use, i am thinking that in my next one year visit i will start Injection therapy to ump start getting back to normal soon.
it might be also a slower healing process for my nerves since i had
open surgery and my nerves probably were touched and pulled more than the less invasive Robotic RP as yours was ...
Good Luck and keep us posted
