Leg swelling can occur at any part of the leg, from thigh to knee to feet. If there is an obvious reason of your leg swelling, such as prolonged standing, sitting, or injury, it is relatively harmless in the long run. If no obvious reason, serious disorders such as edema or blood clot is possible. Therefore, finding the right cause of leg swelling is very important.
By answering questions about your condition, you can find the causes.
