I fell off a roof last July, Approx 20 feet, landed on left foot, had open/closed fracture on inner left ankle, put a cast on said would be o.k./had ankle fusion and calcaneal osteomoty on April 8th of this year, surgeon also shaved and shimmed one side of heel due to parameters needed. Initial diagonisi was shattered heel, broken ankle, broken foot, it's been 3 months since surgery, am in more pain now, that when accident occured. Feels like I am walking on the inside of my left ankle/very painful-any suggestion? should I have an MRI?
