Top 7 Warm Red Foot Swelling Causes

  1. 1.Foot Sprain

    The bones of the ankle and foot are held together by ligaments, which are bands of tough tissue. A sprain is a type of injury where one or more of the ligaments is stretched too far, causing tiny fibers in the ligaments to tear. In most cases, the ligament does not tear completely.

    You should go to a retail clinic to have the foot sprain evaluated. Most often, minor sprains can be treated by resting the foot, elevating it while sitting or laying down, and applying an ice pack or heat. Over-the-counter pain medication can help as well.

    Rarity:
    Common
    Top Symptoms:
    pain in one foot, limping, foot injury, warm red foot swelling, swelling of one foot
    Symptoms that always occur with foot sprain:
    pain in one foot, foot injury
    Symptoms that never occur with foot sprain:
    recent cutting accident
    Urgency:
    Phone call or in-person visit
  2. 2.Skin Infection of the Foot

    Cellulitis is a common and possibly dangerous skin infection if left untreated. It is typically caused by bacteria living on the skin getting into the skin itself.

    You should visit your primary care doctor as soon as possible for a sick visit. He or she will examine the infection and possibly provide antibiotics.

    Rarity:
    Uncommon
    Top Symptoms:
    fever, foot pain, foot redness, warm red foot swelling, swollen ankle
    Symptoms that always occur with skin infection of the foot:
    foot redness, foot pain
    Urgency:
    Primary care doctor
  3. 3.Chronic Foot Bone Infection (Osteomyelitis)

    Osteomyelitis of the foot is a bacterial or fungal infection of the foot bones, typically caused by Staph Aureus (40-50% of the time). It is difficult to diagnose as the infection can come from a break in the skin at the area or anywhere else in the body that spreads by blood.

    You should seek immediate medical care at an ER, where diagnosis of osteomyelitis can be established through x-rays and culturing fluids. Treatment involves antibiotics and removing the infected tissue (by surgery).

    Rarity:
    Rare
    Top Symptoms:
    warm red foot swelling, spontaneous foot pain
    Symptoms that always occur with chronic foot bone infection (osteomyelitis):
    diabetic foot ulcer, spontaneous foot pain, warm red foot swelling
    Urgency:
    Hospital emergency room

  4. 4.Acute Bone Infection of the Foot (Osteomyelitis)

    Osteomyelitis of the foot is a bacterial or fungal infection of the foot bones, typically caused by Staph Aureus (40-50% of the time). It is difficult to diagnose as the infection can come from a break in the skin at the area or anywhere else in the body that spreads by blood.

    You should seek immediate medical care at an ER, where diagnosis of osteomyelitis can be established through x-rays and culturing fluids. Treatment involves antibiotics and removing the infected tissue (by surgery).

    Rarity:
    Rare
    Top Symptoms:
    spontaneous foot pain
    Symptoms that always occur with acute bone infection of the foot (osteomyelitis):
    diabetic foot ulcer, spontaneous foot pain, warm red foot swelling
    Urgency:
    Hospital emergency room
  5. 5.Charcot Arthropathy of the Foot

    Charcot Arthropathy of the foot is a syndrome where patients with numbness of their feet, which can be caused by a variety of underlying conditions such as diabetes, develop weakening of the bones in the foot and ankle. Thus they may have fractures and dislocations of the bones and joints that occur with little trauma.

    You should visit your primary care physician who will likely coordinate care with a muscle and bone specialist (orthopedic surgeon). Treatment usually involves a protective split, walking brace, or cast.

    Rarity:
    Rare
    Top Symptoms:
    joint pain, painful foot swelling, constant foot swelling, pain in one foot, warm red foot swelling
    Symptoms that always occur with charcot arthropathy of the foot:
    warm red foot swelling, constant foot swelling
    Urgency:
    Primary care doctor
  6. 6.Disseminated Gonococcal Infection

    Disseminated gonococcal infection (DGI) is an infection from a sexually transmitted bacteria known as Neisseria gonorrhoeae. It spreads to distant parts of the body beyond the original portal of entry and usually manifest by rash and arthritis.

    You should visit your primary care physician to confirm the diagnosis and discuss treatment options for managing symptoms.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, joint pain, fever, chills, moderate fever
    Urgency:
    Primary care doctor
  7. 7.Kohler Bone Disease

    This is a rare disease of unknown cause. In Kohler disease, the navicular bone (one of the bones of the foot near the ankle) loses its blood supply. The living tissues of this bone die due to lack of oxygen and nutrients.

    You should visit your primary care physician to confirm the diagnosis with an X-Ray. Usually no treatment is needed, however. A weight-bearing cast may improve symptoms, so it is recommended for you to use one for 6-7 weeks.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous foot pain, pain in the top of the foot, swelling of the top of the foot, pain in the inside of the foot, limping
    Symptoms that always occur with kohler bone disease:
    spontaneous foot pain
    Symptoms that never occur with kohler bone disease:
    fever, foot pain from an injury, warm red foot swelling
    Urgency:
    Primary care doctor
