Swollen leg, what can cause this besides a blood clot? How can you tell a blood clot?

In brief: Pain and swelling

Commonly, blood clots cause pain and swelling but sometimes they will only cause one or the other. Occasionally, they cause no symptoms.
Ultrasound is the only way to know for sure, as dr. Korona said. Unfortunately, d-dimer results can be unreliable.

In brief: Multiple

It depends on if it's one-sided or both.
One-sided can be DVT (clot), lymph blockage, venous injury, various cysts. If both, can be heart, liver or kidney failure, poor venous or lymph drainage, among other. Best to see doctor. They can diagnose with ultrasound and/or d-dimer blood test, depending on their judgment.

In brief: With an ultrasound

If you have only one of your two legs swollen, you should have an ultrasound which can show a blood clot.
There are other causes too, but i'd have to know more about you to tell you what would be likely. See your doctor, this could be serious!
