This pain is usually felt to be pronounced on the inner side of the arch from the ankle to the midfoot. The ligament is a discrete pain behind the ankle and is present with passive and active motion. Concern is noted when the tendon is torn, in this case, the patient has difficulty maintaining stance.

Yes. Although the name of the tendon is posterior tibial tendon - the majority of the time the patient has pain it is actually under the ankle or on the inner part of the foot or arch where it inserts in the navicular. So, location of pain can help differentiate the ligament would be located posterior or in back of the ankle, and hence its symptoms as well.
Yes. Posterior tibial tendonitis will cause pain that extends from the ankle to the back arch area of your foot. This will be made worse when you press on the navicular bone when lifting your foot up and inward. There is usually swelling along the tendon. Posterior tibtalar tear will have pain in the back of the ankle area, that is worse with side to side motion and pronating your foot.
