Top 10 Calf Skin Changes Causes

  1. 1.Non - Specific Dermatitis (Skin Inflammation)

    Dermatitis is the inflammation ("-itis") of the skin ("derma" is a layer of the skin). It can be caused by any number of causes, from allergies to infections to autoimmune issues. Dermatitis of Normal Variation (also called, "NOS") means that all of those other causes of your rash have been ruled out. This is very common.

    You can treat this at home and the rash should go away on its own. In the meantime, you can use an anti-histamine (both by mouth OR as an ointment), or a topical corticosteroid to treat the itch and/or pain due to the rash.

    Top Symptoms:

  2. 2.Non - Specific Skin 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.

  3. 3.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

  5. 5.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 most often affects skin of the hands, and may occur after repeated and prolonged exposure to substances such as water, detergents (soaps, bleach), solvents (such as gasoline), acids, powders, dust, and soil. The onset of the skin reaction is usually within 48 hours of coming in 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.

    Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium tuberculosis, which most commonly affects the lungs, although it can also affect other organs in the body.

    You should visit your primary care physician in the next few days. Blood, tissue, and imaging tests can be completed to confirm the diagnosis. If confirmed, a treatment plan can be made to manage the effects of the disease. Results vary with treatment and are dependent on the extent of the deposits.

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.
