When to Call A Doctor

Seek immediate medical attention if you begin to have difficulty breathing or develop hives, a fever, a fast pulse, confusion or nausea. These could be signs of a life-threatening allergic reaction.

Always consult your doctor promptly if a rash:

  • Worsens

  • Lasts longer than one week

  • Shows signs of local infection (oozing, redness or swelling of the skin)

  • Occurs together with fever, chills, swollen glands or other symptoms of infection (sore throat, cough, headache, nasal congestion, etc.)

  • Occurs together with symptoms that suggest an autoimmune disorder, such as recurring fever, malaise, fatigue, unexplained weight loss or joint swelling
