Traction and dorsal nerve in penis

[Tombone]

Hey.
Now I have been using male Edge for 9 days. Yesterday I had this bad aching on the dorsal side of the penis, where my injury was. Today I have back pain and this vibrating sensation in my left bottocks (not sure how to explain this in english) it seems for me that the pressure from traction and the rubberband pressing on the glans irritates the dorsal nerve that goes all the way to the low spinal cord. Not sure if I can do traction anymore. This crap sucks.

Anyone had similar issues with traction and nerve irritation and/or back pain?
It' s actually pretty much, tho even worse, than straight after my injury.
