Hi thanks for asking question. The healing will take still few weeks as injury seems to be serious according to history given by you. First rule out diabetes by doing random blood sugar.If diabetes present healing might delayed. Second do your blood examination also, it may reveal high count suggestive of infection.it also reveal anemia that also delay healing. Malnutrition may delay healing. So Take healthy nutritional diet with vitamin c reach fruit also like orange. Take enough rest and avoid heavy weight lifting. Avoid smoking.If inflammation more at site brufen can be taken. Wish you fast recovery with good health
