<s>[INST] My daughter fell about 3 weeks ago and landed face first on a wooden bench.  She developed a bad bruise which had started to turn yellow.  Today it is back to being black and blue again and there is now a hard lump and her cheek has a little dent in it.  What does this mean and what should I do? [/INST] Hi. Thanks for your query. There are many stages through which a wound healing takes place. Every person's response and outcome to a given injury is different. In case of your daughter, the wound is going through the normal stages of healing and getting hard is indicative of organization of a hematoma. Please give her anti-inflammatory medicines and multivitamins for a better recovery, avoid exposure to the extremes of cold and / hot. No local applications at all, they do not help. You may consult a cosmetic/ Plastic surgeon since the patient is a female (daughter) and needs proper care. </s>
