Top 5 Swelling in One Lower Leg Causes

  1. 1.Blood Clot Requiring an Ultrasound

    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.

    Go to the emergency room immediately.

  2. 2.Fibular Stress Fracture

    The fibula is the smaller shin bone which lies on the outer part of the lower leg. With excessive, repeated stress, a small fracture (called a stress fracture) can occur.

    You need to get your injury checked by a physician, sometimes a MRI scan is needed to confirm the diagnosis. It may be helpful to consult with a physical therapist as well. The treatment for a stress fracture involves avoiding repeated stress on the leg, which means cutting down on high-intensity activity. Exercise that puts less repeated stress on the leg, such as cycling or swimming, is recommended.

    Rarity:
    Rare
    Top Symptoms:
    foot numbness, shin pain, lower leg numbness, pain in the outside of the shin, pain in one shin
    Symptoms that always occur with fibular stress fracture:
    pain in the outside of the shin, pain in one shin
    Symptoms that never occur with fibular stress fracture:
    pain in both feet, pain in one foot, pain in the inside of the shin, swelling in both shins
    Urgency:
    Primary care doctor

  3. 3.Supraventricular Tachycardia

    Supraventricular tachycardia (SVT) is a form of arrhythmia that causes the heart to beat too quickly and begins in the heart's upper chambers. The most common symptoms include a racing heart, lightheadedness and palpitations.

    You should visit a physician today to get an EKG to confirm this diagnosis.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, racing heart beat, lightheadedness, deep chest pain, behind the breast bone
    Symptoms that always occur with supraventricular tachycardia:
    abnormally high heartrate
    Urgency:

  4. 4.Mononucleosis Infection

    EBV Mononucleosis is a clinical syndrome characterized by fever, sore throat, and swollen lymph nodes.

    You should visit your primary care physician within the next 24 hours. Diagnosis is confirmed by looking for antibodies against EBV. Treatment involves supportive care (hydration, antipyretics, and analgesics, such as acetaminophen and ibuprofen). Aspirin should not be given to children because of the possibility of Reye syndrome. It is also recommended that you do not do any strenuous physical activity and contact sports in the initial 3 to 4 weeks of illness due to the potential for splenic rupture.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, abdominal pain (stomach ache), cough
    Symptoms that never occur with mononucleosis infection:
    rectal bleeding
    Urgency:

  5. 5.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.

    You can treat this at home with R.I.C.E - rest (exercise as tolerated), ice (10-20 minutes at a time), compression (this is pretty optional), and elevation (put your feet up to help blood flow back to the heart using gravity).

    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
