For weeks I was convinced that I had an Achilles tendonosis-type injury. That changed on Friday when I visited M.C. Dion, a supremely talented physiotherapist located at McGill's sport medicine clinic. Though I suspected there was something different about this injury compared to the time I (actually) had an Achilles problem, her visit put any doubt to rest. After a few minutes of prodding she confirmed it was the muscle/tendon behind the Achilles causing problems: the Tibialis posterior muscle, or tib-post for short. When M.C. added an electrical current to the muscle, the same tingling sensation was present as when it first started healing (slowly) on its own. A day after her visit it already felt better (though it still needs time to heal). Were these the middle ages, I imagine physiotherapists would be suspect of witchcraft sooner than doctors.
