I'll have to find some pics of the anatomy on the net, put them into my graphics and colorize them. This will take some time.
I'll make a new thread. (it is not an easy task).

In the meantime--- this link shows a side view of the tarsal ligament:

The placement of the patch for the ankle area is just at the pointer of the the yellow arrow. I have used just above the bone, and just below the bone placement successfully. The nerves from the feet bundle there to go up
the leg. When that ligament is tight, from hypothyroidism deposits, or from fluid retention, or scars from injuries, it compesses the nerves going to the foot. If a doctor injects lidocaine here at this point, it will numb the whole foot. That is why the patches work here the same way, only they are not strong enough to totally numb the foot. I had a lidocaine+ steroid shot in my left ankle once...it lasted almost a day, and I couldn't even walk right! Talk about NUMB. (this was inflammation from a nasty spider bite).

My son had the pronation that is also in that article. When we had orthotics made for him, all his pain went away.
