Injury or surgery involving the leg, ankle, or foot can also cause swelling. Swelling may also occur after pelvic surgery, especially for cancer.
Long airplane flights or car rides, as well as standing for long periods of time, often lead to some swelling in the feet and ankles.
Swelling may occur in women who take estrogen, or during parts of the menstrual cycle. Most women have some swelling during pregnancy. More severe swelling during pregnancy may be a sign of preeclampsia, a serious condition that includes high blood pressure and swelling.
Your treatment will focus on the cause of the swelling. Your provider may prescribe diuretics to reduce the swelling, but these can have side effects. Home treatment for leg swelling that is not related to a serious medical condition should be tried before drug therapy.
