It is possible to limit the stim to the one leg, bypassing the trouble between the legs which can be more trouble than worth as you mentioed. No need to take healthy tissue and render it susceptible to those kinds of things. So, keep that smile, it should be susceptible to resolution, either by programme tweak or a revision if that becomes necessary. I know one of my programs works only a single leg, and I set it up that way purposely, and this is while my paddles are also programmed to hit other areas as well. Thus for me it is a selection between programme.
Keep your smile,
