Hello, I was hit in the back of my right leg about 10 days ago by the chair lift that I was loading myself onto (Skiing)... the entire 4 person chair lift hit my leg before making contact with anyone... it was very painful on impact. I am writing because I just went to the ER because the pain has not subsided... it s actually gotten worse. No bruise ever appeared - which amazes me. But I have a throbbing, radiating achy pain from my foot to my hip... but mainly located behind my right knee and along my right calf and in my right foot. It is painful to walk... They took an X-ray - no break. And they did an ultrasound to look for a blot clot.... they saw nothing. But the pain is just getting more noticeable... and it is not located only where I got hit. It s around my knee. I am limping a bit now... and nervous. I feel like I might have a clot and they missed it... what would you suggest as my next move?
