Earlier this week I started having pain in my groin area on the left side and still have it. My left leg is swollen above the knee and very tender. Has anyone ever experienced this? What are the symptoms of a clot in the leg? I had similar experience years ago in my right leg after a complication from a biopsy that caused me to bleed. The only clotting event I've experienced was in 2005 when I got nicked in the carotid artery during my first attempt at heart surgery. I developed a hematoma in my neck that had to be extracted.
