Toxic Shock Syndrome (TSS) is a rare, life-threatening medical emergency caused by toxins produced by Staphylococcus aureus or Streptococcus pyogenes bacteria. You should seek immediate emergency medical care if you experience a sudden high fever, low blood pressure, and a widespread sunburn-like rash, as these symptoms can escalate rapidly. What are the early signs and symptoms of Toxic Shock Syndrome? Recognizing the onset of Toxic Shock Syndrome is critical because it progresses quickly.
Toxic Shock Syndrome (TSS) is a rare, life-threatening medical emergency caused by toxins produced by Staphylococcus aureus or Streptococcus pyogenes bacteria. You should seek immediate emergency medical care if you experience a sudden high fever, low blood pressure, and a widespread sunburn-like rash, as these symptoms can escalate rapidly.
Recognizing the onset of Toxic Shock Syndrome is critical because it progresses quickly. While often associated with tampon use, Toxic Shock Syndrome can occur in anyone following a surgical wound infection, burn, or skin lesion. Early symptoms typically include a sudden fever (often above 102°F/38.9°C), vomiting, diarrhea, muscle aches, and a drop in blood pressure that may cause dizziness or fainting.
If you suspect you have Toxic Shock Syndrome, monitor your body for these specific, rapid-onset markers:
Toxic Shock Syndrome is a medical emergency. Do not wait to see if symptoms improve. If you have recently had surgery, a skin infection, or have been using internal sanitary products and develop a high fever coupled with a rash or dizziness, go to the nearest emergency department immediately. Tell the triage nurse: "I am concerned about Toxic Shock Syndrome and I have a sudden high fever and rash."
There is no single "TSS test." Physicians diagnose Toxic Shock Syndrome clinically based on the CDC criteria, which involve monitoring organ system function. They will likely perform blood cultures, wound cultures, and blood panels to check your white blood cell count, kidney function, and liver enzymes.
