Top 4 Knee Itch Causes

  1. 1.Eczema (Atopic Dermatitis)

    Eczema is a form of skin inflammation that causes skin to be dry, itchy, red, and irritated.

    You should go to your local pharmacy or retail clinic to be treated. The usual treatment for atopic eczema involves avoiding irritants and other triggers, using moisturizers to prevent inflammation, as well as steroid creams and ointments when the inflammation flares up.

    Rarity:
    Common
    Top Symptoms:
    trouble sleeping, feeling itchy or tingling all over, dry skin, scalp itchiness, flexor surface rash
    Symptoms that never occur with eczema (atopic dermatitis):
    fever
    Urgency:
    Phone call or in-person visit
  2. 2.Allergic Contact Dermatitis of the Knee

    Allergic contact dermatitis is a condition in which the skin becomes irritated and inflamed following physical contact with an allergen. Common products known to cause allergic dermatitis include plants, metals, soap, fragrance, and cosmetics.

    You can safely treat this condition on at home. 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:

  3. 3.Dermatofibroma

    Dermatofibroma (superficial benign fibrous histiocytoma) is a common cutaneous nodule of unknown etiology that occurs more often in women. Dermatofibroma frequently develops on the extremities (mostly the lower legs) and is usually asymptomatic, although pruritus and tenderness can be present

    You do not need treatment for this condition because it is completely benign; however, if the lesion changes at all, a doctor should be consulted. If you would like it removed, a doctor can cut, freeze, or burn it off.

    Rarity:
    Rare
    Top Symptoms:
    knee itch, skin-colored knee bump, small knee lump, marble-size knee lump, pink or red knee bump
    Urgency:
    Wait and watch
  4. 4.Insect Bite From a Chigger

    Chiggers are mites that feed on humans and animals only while they are larvae, or their infant form. People can contract chiggers when they contact infected grass. Chiggers feed for three to four days on a piece of skin, and secrete a fluid that causes intense itching.

    You should go to a retail clinic to be treated, as household remedies aimed at killing the mite are unlikely to be effective. The infected area should be kept clean with soap and water. A hydrocortisone cream or local anesthetic may be helpful to reduce the itching. You should avoid scratching the wounds!

    Rarity:
    Rare
    Top Symptoms:
    lower leg itch, constant skin changes, itchy rash, knee itch, lower leg redness
    Urgency:
    Phone call or in-person visit
