Reasons Why Only One Foot Can Become Swollen

Experiencing swelling in one foot can be a perplexing and discomforting issue with various underlying causes. Trauma, such as a sprain or injury, often leads to localized swelling, restricting fluid flow in the affected area. Deep vein thrombosis, a blood clot in the leg, may cause one foot to swell due to compromised circulation. Inflammatory conditions like arthritis can contribute to unilateral swelling, affecting the joints and soft tissues. Lymphatic issues, such as lymphedema, result in fluid retention and swelling, predominantly on one side. Foot infections, including cellulitis, can lead to localized swelling as the body responds to the infectious agents. Vascular problems, like peripheral artery disease, may cause poor blood flow to one foot, resulting in swelling. Understanding the reasons is critical for seeking timely medical attention, as addressing the underlying cause is essential in managing and alleviating the swelling in a singular foot. If you have one foot that is swollen, it is strongly suggested that you consult a podiatrist who can determine the cause and offer effective relief and treatment options.

Swollen feet are a common ailment among pregnant women and people who stand or sit for extended periods. Aging may increase the possibility of swollen feet and patients who are obese often notice when their feet are swelling too. There may be medical reasons why swollen feet occur:

  • Phlebitis - A condition that causes the veins to become inflamed and can also cause leg pain.
  • Liver disease - This may lead to low blood levels of albumin which is a protein. This can cause fluid in the blood to pass into the tissues and several areas of the body can become swollen.
  • Heart failure - When the heart doesn’t pump properly the blood that is normally pumped back to the heart can pool in the veins of the legs causing swollen feet.
  • Kidney disease - One of the main functions of the kidneys is releasing excess fluid in the body. This type of condition can make it difficult for the kidneys to function properly, and as a result the feet may become swollen.
  • Deep-vein thrombosis (DVT)- This is a serious condition where blood clots form in the veins of the legs. They can block the return of blood from the legs to the heart which may cause the feet to swell. It is important to be treated by a podiatrist if this condition is present.

Swollen feet can also be caused by bone and tendon conditions, including fractures, arthritis, and tendinitis. Additionally, there may be skin and toenail conditions and an infection may cause the feet to swell. Patients who take medicine to treat high blood pressure may be prone to getting swollen feet. 

Many patients elevate their feet to help relieve the swelling and this is generally a temporary remedy. When a podiatrist is consulted the reason behind the swelling can be uncovered and subsequently treated.
