This has also resulted in really poor ankle mobility, especially in my left
foot, and severly reduced dorsiflexion (that too in my left
foot). My left foot also tends to fall inwards.
Years ago, before developing all of these symptoms, I underwent a rather thourough Neurexamination (because of functional weakness, numbness etc, mostly prominent in the left side of body).
Several Doctors concluded that I suffer from hemsensory conversion disorder or something along those lines.
