When should you go to the emergency room? Warning signs you shouldn't ignore.

May 25, 2026

Often, people are unsure whether a health situation requires immediate attention or can wait for a scheduled medical appointment. Knowing when to go to the emergency room can make a significant difference in a patient's outcome and allow for timely care in potentially serious situations.

At Clínica Hospital San Fernando, we have a 24-hour emergency room, prepared to handle medical emergencies with trained personnel, medical technology, and quick access to diagnostic and specialized services.

Recognizing warning signs and acting in time is one of the most important decisions to protect your own health and that of your family.

What is a medical emergency?

A medical emergency is any condition that requires prompt attention to prevent complications, further damage, or risk to the patient's life. Some emergencies are obvious, while others may begin with seemingly mild symptoms that rapidly escalate.

For this reason, it is important not to minimize certain body signals and to seek professional evaluation when there are doubts.

 
Warning signs that require immediate attention

 

There are symptoms that should never be ignored and that justify going immediately to the hospital or the emergency room.

Severe chest pain

One of the most important symptoms is intense pain or pressure in the chest, especially if accompanied by:

  • Difficulty breathing.
  • Excessive sweating.
  • Dizziness.
  • Pain that extends to the arm, neck, or jaw.

These symptoms may be related to cardiovascular problems that require immediate evaluation.

At Clínica Hospital San Fernando, the emergency department has the support of:

  • Internal medicine.
  • Cardiology.
  • Clinical laboratory.
  • Diagnostic imaging studies.

This allows for rapid action in cardiovascular emergencies.

Difficulty breathing

The sensation of shortness of breath, rapid breathing, or difficulty getting oxygen may be related to:

  • Asthma attacks.
  • Respiratory infections.
  • Heart problems.
  • Severe allergic reactions.

Early intervention is essential to stabilize the patient and prevent complications.

Loss of consciousness or fainting

Sudden fainting, loss of consciousness, or episodes of confusion may indicate neurological, cardiovascular, or metabolic disorders that require urgent evaluation.

In these cases, the hospital can supplement care with:

  • Laboratory studies.
  • CT scans.
  • Resonances.
  • Specialized clinical monitoring.
Heavy bleeding

Bleeding that does not stop or is very heavy should be treated immediately, especially if it occurs:

  • After an accident.
  • During pregnancy.
  • After surgery.
  • Accompanied by dizziness or extreme weakness.

Timely management can prevent major complications.

Persistent high fever

Although many fevers can be managed at home, a high fever accompanied by symptoms such as:

  • Seizures.
  • Difficulty breathing.
  • Stiffness in the neck.
  • Dehydration.
  • Confusion.

Requires immediate medical evaluation.

Accidents and injuries

Hard blows, falls, traffic accidents or sports injuries can cause internal damage that is not always visible.

At Clínica Hospital San Fernando, patients have access to:

  • Radiology.
  • Tomography.
  • Ultrasound.
  • Surgical care.
  • Equipped operating rooms.

All of this facilitates fast and coordinated care.

 

When should I go to a primary care clinic or general practitioner?

Not all discomforts require emergency care. Some situations can be initially evaluated at:

  • General medical consultation.
  • Primary care.
  • Scheduled specialist consultations.

For example:

  • Mild colds.
  • Moderate muscle pain.
  • Medical check-ups.
  • Monitoring of chronic diseases.
  • Preventive assessments.

Primary care allows for continuous and personalized monitoring of the patient's health.

The importance of not self-medicating

One of the most common mistakes is ignoring symptoms or trying to manage them without medical supervision. Self-medication can:

  • Hiding important symptoms.
  • Delaying diagnoses.
  • To cause adverse reactions.
  • Complicate subsequent treatments.

If you experience persistent or worrying symptoms, it is best to seek professional evaluation.
