[|Human|] 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
[|AI|]  Dear patient Where is the swelling?  If it's lying on outer aspect of thigh its not great saphenous vein as it is deep and lies on inner aspect of thigh. So first we have to confirm diagnosis.  I would like to advise ultrasound and venous Doppler of your thigh to confirm diagnosis. If its superficial blood clot only it will take time to disappear. Even if its thrombophlebitis of superficial vein swelling may persist for months. Visit radiology center nearby you and get it done.  You need to consult vascular surgeon with report.  All the best.
