Yes, it's quite possible your hedgie is sucking or biting on her feet. They probably feel funny to her - maybe irritated or itchy as the wounds scab over. Provided there is no sign of infection, you can try putting vaseline on them.
Without the sucking or biting, and with wheel removed, I'd expect little foot wounds to heal in less than a week. With the sucking or biting... gosh... it could take a long, long time if she keeps irritating the areas.
I should ask: how did she get these cuts in the first place... If whatever caused it is still present, she could routinely re-injure herself in the same way.
