Lower leg swelling: Long periods of sitting or stillness can lead to blood clots in the leg veins. Usually one lower leg swells compared to the other side. You can measure with a tape measure at the same place on each leg and determine if one side is an inch or more different from the other.

Can be hard to tell: 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.

Pain is key, worse: When flexing/extending ankle. Is one leg larger than the other? Call your doc if so or go to urgent care. U/s next, used to require venogram now rarely if ever done. The risk is dislodged clot, piece traveling to lung causing pulmonary embolus. Can be lethal.
