Probably not: Generally, clots occur because you have 1) a blood condition that promotes clotting or 2) you've been traveling or had a medical problem and were immobile for a long time. If your leg isn't swollen or red, it's probably not a clot. Leg pain can be due to many things. Clots don't make any noise. But if you're concerned see your doctor, who might order an ultrasound if indicated by your exam.
