certainly wait till 8th of september as that completes 6 weeks , get an X-ray done just to know the status of callus formation i believe you can even join before october by 15th or so , if everything goes well that is if callus formation is good.
Next Steps
continue with the therapy sessions. and ask the orthopaedic. about the load that you may be able to take.
Health Tips
Dont just overload the weal callus , and respect pain, Ankle pump exercises will keep swelling at bay. so continue that. and STAY HEALTHY
