I tripped/stumbled/crashed/had accident while wearing a traction device

[Cowboy James]

I crashed my knee into a coffee table while wearing my extender. I was just walking in the sitting room; I can be a bit of a klutz. The jolt caused the extender to pull on my penis and it hurt quite a bit. I took it off immediately. If anyone knows, what is the best treatment for this? Have I caused any permenant damage? For the moment I am not using it, of course. Replies appreciated.

I'd just apply ice for a few hours being careful not to over do it.  Wrap the ice in a cloth and then apply to the injured area for ten minutes on 5 minutes off.  
If it gets black and blue you'll need to see your urologist.
