Rashes

A rash is a change in the skin that can result in redness, itching, swelling, and/or blistering. Rashes can be caused by a variety of factors, including infections, allergies, autoimmune disorders, and exposure to certain substances.

Types of Rashes

  • Contact Dermatitis: a rash that occurs when the skin comes into contact with an allergen or irritant, such as poison ivy or soap.
  • Eczema (Atopic Dermatitis): a chronic skin condition characterized by itchy, inflamed skin, often caused by allergies or asthma.
  • Psoriasis: an autoimmune disorder that causes red, scaly patches on the skin, often on the elbows, knees, and scalp.
  • Heat Rash (Prickly Heat): a rash that occurs when the skin is exposed to high temperatures and humidity, causing sweat glands to become blocked.
  • Rosacea: a chronic skin condition characterized by redness, acne-like symptoms, and visible blood vessels on the face.
  • Impetigo: a highly contagious bacterial infection that causes red sores on the skin, often on the face, arms, or legs.
  • Ringworm (Tinea): a fungal infection that causes a ring-shaped rash on the skin, often on the body, scalp, or feet.
