4. Chest Pain or Pressure
Chest pain is one of the most common symptoms of a heart attack, but it can also indicate angina, blood vessel problems, or inflammation around the heart or lungs. If the pain feels like pressure, tightness, squeezing, or burning—and especially if it radiates to the left arm, neck, jaw, or back—do not delay. Immediate attention can save your life.
5. Sudden Confusion or Disorientation
Sudden changes in mental status—such as confusion, difficulty speaking, or memory loss—are often signs of a stroke, brain tumor, or severe infection (like sepsis). In older adults, even a urinary tract infection can cause acute confusion. If you or someone you know seems mentally altered or is behaving strangely, don’t wait—call emergency services.
6. Severe or Persistent Abdominal Pain
A stomach ache isn’t always just indigestion. If you experience sharp, persistent, or radiating abdominal pain—especially with vomiting, fever, or swelling—it could indicate internal bleeding, appendicitis, pancreatitis, or gastrointestinal perforation. These are medical emergencies that can become fatal if left untreated.
7. Uncontrolled Bleeding or Easy Bruising
