Be wise, PTC.

1.  Get your knee checked out by your doctor.

2.  Start writing and let your knee talk to you.  Set  up a conversation that goes:

PTC:    

Knee:

PTC:  

Kenn:

and let yourself be surprised by what comes.  

Thank you for sharing this!

We can't tell if it's mind to body or body to mind or a combination with two way traffic.  So explore as much as you can.  :)
