I am trying to determine whether to go to the emergency room or wait until morning to schedule a doctor appointment. I was sitting in a recliner watching TV when I got an extremely sharp pin in my right leg on the front just to the left of my shin. It was extreme and then the area begin swelling. It is still swollen and extremely sore to touch. I took 1000 mg of aspirin because I thought it might be a blood clot. I had hip surgery nine months ago. It is still extremely painful. It is still swollen. I am able to walk on the leg. Trying to decide if emergency room visit is warranted. It seems that it is getting numb below the area.
