Lymphedema

Lower leg swelling is a common concern brought to primary care doctors. While leg swelling can be a sign of other underlying disorders, such as blood clots and heart failure, it is also commonly caused by lymphedema. Lymphedema is an accumulation of fluid and/or adipose tissue as a result of an issue with the body’s lymphatic drainage system. Often the underlying issue is from damage from something like an injury, surgery, cancer treatments, or lymph node removal, but other times the cause is genetic, hereditary, or simply unknown.

The swelling with lymphedema generally starts slowly and progresses. At first it is usually ‘pitting,’ which means the kind of swelling you can poke with your finger and see the finger mark remain. As the swelling progresses and becomes more chronic, it may no longer be pitting but rather measures as an increase in circumference of the extremity. Often the swelling is asymmetric, with one leg or arm measuring bigger than the other.

Sometimes patients with lymphedema complain of a heavy sensation in the affect limbs, with aching discomfort and stiffness. Depending on the degree and duration of swelling, rashes and other skin lesions can develop. Others are primarily bothered by the appearance. Either way, treatment options are available! Exercising the affected limbs helps to prevent swelling from getting worse. It is also recommended to wear compression garments, including with exercise. I have also had patients see great results going to a lymphedema center, where a specialized physical therapist does manual lymphatic drainage massages.

If you are having concerns about lower leg swelling, definitetly make an appointment with your doctor! Your PCP can help rule out the more dangerous threats, and then guide you towards the best way to manage going forward!
