Hives, also known as urticaria, is a common skin reaction that causes the appearance of itchy red welts on the skin. The welts can vary in size and can appear anywhere on the body.

Signs Your Rash Requires Immediate Medical Attention

A rash is a common skin condition that can be caused by a variety of factors, such as allergies, infections, or autoimmune disorders. While most rashes are harmless and will clear up on their own, some can be serious and require immediate medical attention.

Here are 10 signs that your rash requires immediate medical attention:

You have a fever. A fever is a sign that the body is fighting an infection. It’s important to take a fever seriously, especially if it’s accompanied by a rash. A rash is often a sign that the infection is getting worse.

  • The rash is painful. A painful rash is most often a sign of an infection. Infections that can cause a painful rash in the affected area include skin infections, such as impetigo or cellulitis, and other infections, such as pneumonia or meningitis. A painful rash can also be a sign of a skin allergy or a skin condition, such as eczema or psoriasis.
  • The rash spreads to the entire body. This type of rash can be indicative of a serious infection or other medical emergency and requires prompt evaluation by a healthcare professional. Some of the most common causes of a body-wide rash include sepsis, meningitis, and Henoch-Schönlein purpura.
  • The rash appeared suddenly. If you have a sudden rash on your skin, it is important to make sure that it does not indicate an infection or other medical emergency. If you experience a painful rash in the past, check with your doctor about it if you develop one again.
  • You have difficulty breathing. A rash that may cause difficulty breathing should be evaluated by a healthcare professional. If you have trouble breathing, seek immediate medical attention if it does not go away quickly.
  • The rash is blistering. A rash that is blistering may indicate a serious infection, such as sepsis. If there are blisters and you develop a fever, seek medical attention immediately.
  • The rash has lasted longer than a week. How long do skin rashes last? An ordinary rash will usually go away after a few days. If the rash lasts longer than a week, it should be checked by your doctor.
  • The rash is purplish in color. A rash that is purple in color may indicate an infection.
  • The rash looks like a bullseye and you have had a tick exposure. A rash that looks like a bullseye may be caused by a mite or tick bite.
