[30F] Experiencing chest and throat tightness with fast heartbeat

What might be happening

Based on the symptoms you've described, here are some possible explanations:

• Panic Disorder: This is a type of anxiety disorder characterized by recurrent and unexpected panic attacks. Symptoms can include palpitations, sweating, shaking, shortness of breath, feelings of choking, chest pain, nausea, dizziness, and fear of losing control or dying. The symptoms you've described, such as tightness in your chest and throat, rapid heartbeat, and difficulty breathing, are common during a panic attack. However, panic attacks are typically intense periods of fear or feelings of doom developing over a very short time frame - up to 10 minutes - and they're usually not as long as the 3-4 hours you've described.

  • Treatment typically involves cognitive behavioral therapy and medication management.

• Gastroesophageal Reflux Disease (GERD): This is a digestive disorder that occurs when acidic stomach juices, or food and fluids back up from the stomach into the esophagus. GERD can cause a wide range of symptoms, including heartburn, regurgitation, and trouble swallowing. A less common symptom of GERD is a constant heaviness in your throat, chest tightness, and difficulty breathing.

  • Treatment typically involves lifestyle changes and over-the-counter medications. In some cases, prescription medications or surgery might be needed.

• Heart conditions: Given your family history of heart disease, it's also important to consider cardiac causes for your symptoms. Conditions such as angina or even a heart attack can present with symptoms similar to what you've described. However, these conditions are less likely given your age and lack of other risk factors.

  • Treatment will depend on the specific condition and its severity, but it's crucial to seek immediate medical attention if a heart condition is suspected.

What you can do

Given the severity and duration of your symptoms, it's important to seek medical attention as soon as possible. In the meantime, here are some steps you can take:

1. Try to stay calm. If your symptoms are due to panic disorder, practicing relaxation techniques such as deep breathing, meditation, or yoga might help.
2. Avoid triggers. If your symptoms are due to GERD, try to identify and avoid foods that trigger your symptoms. Also, try to eat smaller meals and avoid eating 2-3 hours before bedtime.
3. Stay active. Regular physical activity can help reduce anxiety and improve heart health.

What you should look out for

Please seek immediate medical attention if you experience any of the following:

• Severe chest pain or discomfort
• Pain or discomfort in your arms, back, neck, jaw, or stomach
• Shortness of breath with or without chest discomfort
• Cold sweat, nausea, or lightheadedness
