Heart attack symptoms can include chest pain or discomfort, shortness of breath, pain in the arm, jaw, neck, back, or shoulder, nausea, lightheadedness, or unusual tiredness. These symptoms may be sudden, but they can also build gradually.
1. Unusual Fatigue
Feeling tired after a long day is normal. But unusual fatigue is different. It may feel heavy, unexplained, or out of proportion to what you did.
Some people describe it as feeling drained after simple tasks, needing more rest than usual, or suddenly struggling with normal daily activities. This type of fatigue may be especially easy to dismiss as stress, age, poor sleep, or overwork.
The source article notes that unusual or extreme fatigue is commonly reported, especially among women.
2. Chest Discomfort or Pressure
Chest discomfort is one of the best-known heart attack warning signs, but it is not always sharp pain. It may feel like pressure, tightness, squeezing, heaviness, burning, or fullness in the chest.
