Hi welcome to health care magic forum .Lucky you could find the plateau fracture
in absence of diagnosis you would have faced many problems. Avoiding weight bearing on the left foot means avoid holding any thing with left hand , don't carry any thing on left shoulder, don't climb up or down the steps quite often, avoid to be in the crowd.
Besides i advise you some diet recommendations as avoid taking potato, other tubers, tomato, coconut, cauliflower, egg, chicken, fish, and other sea foods.
Take more of green leafy vegetables, pulses, sprouts, milk, meat, fruits, juices, and dry fruits to improve blood general health, resistance against infections, and stamina to withstand such pains. Wishing for a quick recovery, and thanks for calling.
