7 Common Causes of Itchy Rashes on Legs



Itchy skin causes a lot of irritation. It is characterized by rashes and red bumps on the surface, which can be caused due to several skin conditions or internal illnesses. Red, itchy rash legs are most often a sign of a serious underlying disorder.

 

Normally, these rashes are not a matter of concern and can be treated with the help of effective home remedies and OTC topical ointments. But, it is important to find the exact cause of the rash before starting on any treatment.

Common Causes of Red Itchy Rash Legs

  • Keratosis Pilaris: These are small red or white bumps that appear on the arms and legs. They generally do not itch or itch very less. The skin condition occurs when the skin pores are clogged with a protein called keratin. People with eczema or dry skin are more likely to have keratosis pilaris.
  • Folliculitis: This is a skin condition that occurs as a result of infection in the hair follicles, either in the scalp or in other areas of the body that have been shaved. It is most commonly caused due to a bacteria called Staphylococcus aureus.
  • Eczema (Atopic Dermatitis): If your red itchy, rash legs have red bumps and scaly patches, it is more likely to be an eczema infection. Your skin will become extremely itchy and have blisters that may ooze out a clear fluid.
  • Hives: Hives is another cause of red, itchy rash on legs. Also known as urticaria, hives make the skin red and raised. They are often caused due to a reaction to certain food items, medicines, cold, insects, pollen, or latex.
  • Insect Bites: Red, itchy, rash legs can also be caused due to insect bites, especially if they itch a lot. Common causes include mosquitos, fire ants, fleas, lice, chiggers, bed bugs, and scabies.
  • Psoriasis: This is a chronic condition that causes red, itchy, and scaly patches on the skin. The second most commonly occurring form of this condition is known as guttate psoriasis, which causes reddish and scaly spots on the trunk and limbs.
  • Skin Cancer: Skin cancer is primarily caused by extreme and prolonged exposure to the sun. There are different types of skin cancers that result in red and itchy skin. The most common types include Bowen’s disease and basal cell carcinoma (BCC).

If the itchiness does not go away on its own, it is important to see a doctor for an accurate diagnosis and a suitable line of treatment.
