<s>[INST] My husband was in a car accident 1 week ago, after which he noticed a hard painful lump on his shin. It was swollen and slightly painful. He thought it was going to be a bruise. 1 week later he still has the hard lump. It's still swollen and still hurts. I forgot to mention that 3 or 4 days after the accident he had extreme bruising, on the same leg, just below his ankle bone. That's improving. Does this sound like a blood clot?
