Hi Andrew!
What I have done in the past is place a 1″ needle about 1-2 fingers width into the syndesmosis from the malleoli up as high as they are painful. You can certainly add some stim (2Hz) to the top and bottom needle as well. And then any other contributing factors in the LE or foot and ankle you think would be helpful.
Hope that gets you started! Looking forward to anyone else’s thoughts.
