Hi, You seem to have some problem in your ankle joint, what caused you to start indifferently initially, had you met with any injury. If inversion persists and you are not able to bear your body weight better get x-ray/ MRI of your ankle joint and consult orthopedician for correction.
Hi,
Does it pain much?Consult an orthopaedic surgeon,this type of gait could be due a neurological problems too.You need to be evaluated thoroughly.Do not continue to walk like this, as weight bearing on one limb can eventually lead to other serious complications.
Meet the as early as possible.
Goodluck
