Dangerous Medical Conditions Linked To Swollen Feet


Pregnancy and overworked feet are often common causes of swollen feet.

However, there may be other explanations behind your swollen feet and legs. There are several conditions that can cause swollen feet. In addition, some of those conditions are extremely serious.

So, instead of ignoring your swollen feet, you need to make sure there isn't something going on that needs immediate medical attention.
Here are some of the most dangerous causes of swollen feet:

Deep Vein Thrombosis

According to the Mayo Clinic, "Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs." This condition causes pain and swelling in your legs as well as your feet. Moreover, it can be really dangerous. Here's why: if the blood clots break loose, they can travel through your veins and into your lungs. That can lead to a blockage of blood flow, which can cause a pulmonary embolism. If you have any reason to suspect that you have DVT, seek medical attention ASAP. It is a serious condition.

Achilles Tendonitis

According to the American Academy of Orthopaedic Surgeons, achilles tendonitis is a very common condition. It can cause pain in the heel and back of the leg. What is more, achilles tendonitis can also cause swelling, primarily in the heel and ankle areas. The swelling could be constant, but is more likely to occure after exercising or engaging in physical activity.


This condition is also known as "wear-and-tear" of the body, is the most common form of arthritis. this condition is connected to the breaking down of cartilage, and is age-related. Osteoarthritis in the feet and ankles can cause pain, tenderness, stiffness, and swelling. People who suffer from this affliction may find it difficult to walk or put much weight on their legs.

Heart Failure

Heart failure signs can often be subtle, such as swelling in the feet. The feet swell due to heart failure because of a buildup of fluid, known as edema. According to the American Heart Association, this fluid retention can cause swelling in the legs, feet, and ankles.


According to the Mayo Clinic, "Lymphedema refers to swelling that generally occurs in one of your arms or legs." Common symptoms of lymphedema are aching, discomfort, recurring infections, a tight or heavy sensation, and swelling in part or all of your limb. Lymphedema in your leg can cause severe swelling in the ankle, foot, and toes.


According to the U.S. National Library of Medicine, "cellulitis is an infection of the skin and deep underlying tissues." If this condition is left untreated, it can be potentially life-threatening. It can cause your skin to become swollen, red, and tender, and the area may also feel hot to the touch. This condition can occur anywhere on the body, but more often it affects the lower legs.


Gout is one of the most painful forms of arthritis. It occurs when too much uric acid builds up in the body. A lot of people first notice the symptoms in their big toe, but it can also affect ankles, heels, insteps, knees, wrists, fingers, and elbows. Common symptoms of gout are pain, redness, stiffness, heat, and swelling.

Foot Bursitis

Bursitis is a condition that affects the fluid sacs that cushion your bones, tendons, and muscles. It affects shoulders, hips, and elbows, however it can also affect knees, heels, and big toes. This condition will make the affected joint feel stiff and achy, and it will appear red and swollen. What is more, it will hurt when you move it or press on it.
