My girlfriend's leg is hurt. What should I do for her so that she can feel my concern?

Care comes from the heart ... What you need to do is simple: cook some bone soup every day (preferably tube bone, which has the effect of reinforcing bones), and cook it for her to eat (stir-fried spinach and steamed ribs, which are all helpful for supplementing nutrition, don't scramble eggs, because it is easy to get inflamed). Massage and rub her medicine properly according to the doctor's instructions. Try to talk with her about happy things (jokes or funny things you have encountered, because she will feel lonely if she can't go outside because of her leg injury). Finally, I wish your girlfriend a speedy recovery!
