Rash

A rash is anything that involves changes in the color or texture of the skin. It often starts quickly and is very itchy. Also referred to as dermatitis, skin redness or inflammation or skin lesions, rashes can often be determined from its visible characteristics and other symptoms. Common causes of rashes include:

  • Chemicals in elastic, latex, and rubber products
  • Cosmetics, soaps, and detergents
  • Dyes and other chemicals in clothing
  • Poison ivy, oak, or sumac

Psoriasis

Psoriasis may be passed down through families, but is not contagious. The main symptom of the condition is irritated, red, flaky patches of skin, called scales, which are most often seen on the elbows, knees, and middle of the body, but can appear anywhere including the scalp. If you have psoriasis, your skin may be:

  • May or may not be itchy
  • Dry and covered with silver, flaky skin (scales)
  • Pink-red in color (like the color of salmon)
  • Raised and thick

Psoriasis worsens in the fall and winter months.  If you think your skin condition is more than just a common rash and may be psoriasis, visit your PCP or dermatologist.
