10 Possible Swollen Lower Leg Causes

The list below shows results from the use of our quiz by Buoy users who experienced swollen lower leg. This list does not constitute medical advice and may not accurately represent what you have.

Cellulitis

Cellulitis is a bacterial infection of the deep layers of the skin. It can appear anywhere on the body but is most common on the feet, lower legs, and face.

The condition can develop if Staphylococcus bacteria enter broken skin through a cut, scrape, or existing skin infection such as impetigo or eczema.

Most susceptible are those with a weakened immune system, as from corticosteroids or chemotherapy, or with impaired circulation from diabetes or any vascular disease.

Symptoms arise somewhat gradually and include sore, reddened skin.

If not treated, the infection can become severe, form pus, and destroy the tissue around it. In rare cases, the infection can cause blood poisoning or meningitis.

Symptom of severe pain, fever, cold sweats, and fast heartbeat should be seen immediately by a medical provider.

Diagnosis is made through physical examination.

Treatment consists of antibiotics, keeping the wound clean, and sometimes surgery to remove any dead tissue. Cellulitis often recurs, so it is important to treat any underlying conditions and improve the immune system with rest and good nutrition.

Rarity: Uncommon

Top Symptoms: fever, chills, facial redness, swollen face, face pain

Symptoms that always occur with cellulitis: facial redness, area of skin redness

Urgency: Primary care doctor

Deep vein thrombosis (DVT) is a blood clot that forms in a vein deep in the body. Most deep vein clots occur in the lower leg or thigh.

Ankle sprain

Ankle ligaments, which connect bones to one another, stabilize the ankle joint. A sprain is an injury to the ligaments caused by a twisting motion of the joint.

Rarity: Common

Top Symptoms: pain in one ankle, ankle pain from an injury, swollen ankle, bruised ankle, ankle twisting

Symptoms that always occur with ankle sprain: pain in one ankle, ankle pain from an injury

Urgency: Phone call or in-person visit

Shin bruise

A bruise is the damage of the blood vessels that return blood to the heart (the capillaries and veins), which causes pooling of the blood. This explains the blue/purple color of most bruises. Bruises of the shin are common given the location of the shin.

Rarity: Uncommon

Top Symptoms: shin pain from an injury, shin injury, pain in one shin, shin swelling, shin bruise

Symptoms that always occur with shin bruise: shin injury, shin pain from an injury

Urgency: Self-treatment

Compartment syndrome

Acute compartment syndrome describes the damage done to certain muscle groups of the arms or legs after a traumatic injury.

All of the long muscles are bundled into sections – "compartments" – by the white sheets of strong, tough connective tissue called fascia. If something interferes with circulation so that blood flow is trapped within the compartment, pressure rises because the fascia cannot stretch. This causes serious damage to the muscles and other tissues within the compartment.

Acute compartment syndrome is caused by a broken bone; a crush injury; burns, due to scarred and tightened skin; and bandages or casts applied before an injury has stopped swelling.

Symptoms can rapidly intensify. They include severe pain and tightness in the muscle; tingling or burning sensation; and sometimes numbness and weakness.

Acute compartment syndrome is a medical emergency which can result in loss of the limb. Take the patient to the emergency room or call 9-1-1.

Diagnosis is made through patient history and physical examination.

Treatment involves hospitalization for emergency surgery and, in some cases, skin graft.

Rarity: Rare

Top Symptoms: arm numbness, hand numbness, foot numbness, pain in one leg, thigh numbness

Urgency: Hospital emergency room

Repetitive strain injury of the calf

Repetitive strain injury of the calf is caused by consistent repetitive use.

Rarity: Uncommon

Top Symptoms: lower leg numbness, calf pain from overuse

Symptoms that always occur with repetitive strain injury of the calf: calf pain from overuse

Symptoms that never occur with repetitive strain injury of the calf: recent calf injury, severe calf pain

Urgency: Self-treatment

Calf strain

A strain, commonly called a "pulled muscle," is when a muscle becomes overstretched, and microscopic tears occur. A calf strain happens when one of the muscles on the back of the lower leg is pulled.

Rarity: Common

Top Symptoms: pain in one calf, moderate calf pain, calf pain, sports injury, soccer injury

Symptoms that always occur with calf strain: pain in one calf

Urgency: Self-treatment
