question: I hit my thigh very hard on the edge of a metal piece on a trailer. Did not pierce skin but was excruciating. A few days later the whole greater saphanus vein became infected, raised, bruised and hard. I have since been to ER and found it was superficial blood clot. I m jut wondering why it s raised and hard and why it still hurts after almost 2 weeks. I elevate regularly and use heat pad. I m on 500mg naproxen. Any info you can supply would be very appreciated
