<s>[INST] I injured my shin 2 days ago, at first it was very swollen and there was a grazing, as well as a bit of skin missing with a dark red wound in the middle but no bleeding. Now It is swollen around the wound and a very puffy yellow. with a reddish blue bruising around the swelling. is this going to require medical treatment? [/INST] Hi,I have studied your case There can be bony contusion.And associated hematoma due to soft tissue injury.Use splint or compressive crepe bandage to reduce swelling.Take precaution to avoid infection around hematoma.Yes you should now consult your doctor for clinical examination and rule out any vascular clot.Hope this answers your query.
