Most rashes tend to cause redness, itching and small bumps, reports MedlinePlus. Blisters and patches of raw skin are also common. Many rashes don't require medical treatment and clear up quickly on their own. However, depending on the cause and nature of the rash, it may require long-term treatment. One should consult a medical professional if other symptoms occur or if itching persists over time.

There are many possible causes for a rash to form, including allergies, stress and serious underlying illnesses, such as liver disease, kidney disease and cancer, reports MedicineNet. Infections, such as yeast infections, ringworm, jock itch and psoriasis, may also cause an itchy skin rash. Infestations from parasites such as scabies or body, head and pubic lice are common causes of itchy rash.

Home-care treatments may include moisturizers, lotions, and over-the-counter hydrocortizone or Benadryl, according to MedlinePlus. Additionally, one should avoid scratching and rubbing the area as much as possible; avoid wearing tight fitting clothing or garments that have an abrasive texture, such as wool; and stay out of the sun and extreme heat in order to alleviate the discomfort.
