u said that, suspected # and u cant stand upright with full body weight, that means the texture of the ligaments is not same now as before,they are weak now, if u do theraband(which colour, u have not mention), may be harm full to the suspected #(avulsion # may occur due to over use/pressure further in the same place), it may cause undue pressure to the previously injured ligaments and surrounding soft tissue. so i advised u to stop theraband, and make a further evaluation of ur ankel by a good EXPERIENCED professional. sorry for the late reply. have a good day.
