<s>[INST] Hello, about 2.5 weeks ago I was hit in the left shin quite hard with a softball. It instantly bruised and formed quite a large lump. It is still very sore and while the bruising seems to be going away, the lump is still there. Should I go and have it examined? [/INST] Hi,Welcome to HealthcareMagic .It Is most likely a haematoma underneath. Since it is still sore better to get it examined. If such a patient comes to me I will put on serratiopeptidase with aceclofenac to reduce the swelling . If thick collection then aspiration may be needed.Hope I have answered your query.RegardsDr Deepika Patil </s>
