Top 9 Foot Redness Causes

  1. 1.Irritant Contact Dermatitis

    Contact dermatitis is a condition in which the skin becomes red, sore, or inflamed after direct contact with a substance. This condition may occur after repeated and prolonged exposure to substances such as water, detergents (soaps, bleach), solvents (gasoline), acids, powders, dust, and soil. The onset of the skin reaction is usually within 48 hours of contact with the substance.

    You can safely treat this condition on your own. The main treatment for this disease is to avoid the substance that triggers the skin inflammation. Moisturizer can also be helpful to provide relief for your inflamed skin.

    Rarity:
    Common
    Top Symptoms:
    foot pain, foot redness, thickened skin on the foot, rough skin on the foot
    Symptoms that always occur with irritant contact dermatitis:

  2. 2.Non - Specific Foot Rash

    A rash is an area of irritated or swollen skin. Often, rashes are unidentifiable and some variation of normal. For example, scratching one's arm causes it to turn red (which is caused by mast cells releasing chemicals into the local area), but that's completely normal.

    At this time, you do not need treatment for this rash. If it worsens, you may need to consult a physician.

  5. 5.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.

  6. 6.Severe Frostbite of the Lower Limbs

    Frostbite is tissue damage caused by exposure to the cold (at or below 32F or 0C). It is most commonly found in people doing leisurely activities like camping, hunting, or snow sports. It is also more likely in those who are intoxicated or have a mental disorder.

    Those with suspected frostbite should have wet clothing removed. Rubbing affected areas worsens damage to the tissue. You should go to the ER by car, immediately. If rewarming can occur without chance of refreezing, it can be tried in the field. There, the doctors will guide you in gently re-warming the wounded area in 98-102F (37C-39C) water. Further, ibuprofen, antibiotics, a tetanus shot, and possibly surgery will be done to treat the pain and dead tissue. IV fluids will also be started. Hydrotherapy will be done daily to help with the wounded area.

    Rarity:
    Rare
    Top Symptoms:
    foot pain, foot numbness, swollen foot, limping, toe numbness
    Symptoms that always occur with severe frostbite of the lower limbs:
    cold toe
    Urgency:
    Hospital emergency room
  7. 7.Mild Frostbite of the Lower Leg

    Those with suspected frostnip should have wet clothing removed. Rubbing affected areas worsens damage to the tissue. You should go to an urgent care. If rewarming can occur without chance of refreezing, it can be tried in the field. At urgent care, the doctors will guide you in gently re-warming the wounded area in 98-102F (37C-39C) water.

  9. 9.Necrotizing Fasciitis of the Leg

    Necrotizing fasciitis is a potentially life threatening skin condition stemming from the infection of a wound or injury. If left untreated, it can spread to body parts surrounding the infection changing the color of the skin and degrading the tissue underneath. This can result in muscle, tissue or limb loss and a severe body-wide response to the infection.

    You should visit your local emergency room where blood tests can be run and a consultation can be made by a skin specialist. If caught early, antibiotics, cleaning, and a stay in the hospital can help control the infection. If serious, additionally procedures may be required. It is important to get treatment due to the possibility of this becoming a serious, life-threatening condition.

    Rarity:
    Rare
    Top Symptoms:
    nausea, vomiting, fever, diarrhea, chills
    Symptoms that always occur with necrotizing fasciitis of the leg:
