Chest Discomfort and Numbness During Sleep - Cardiology

Numbness during sleep?


Hello doctor, when I first lie down to sleep, I feel a pressure in my chest, as if blood is pooling in my chest and head.
At that time, my blood pressure is not high.
For the past two weeks, when I wake up, my tongue feels numb, and my head and chest also feel tingling, like a mild electric shock.
My blood pressure was 80/56 and my heart rate was 57.
The numbness increases the longer I sleep, but it improves after I get up.
One time, I woke up in the middle of the night feeling weak all over, and I often experience dizziness and cold hands and feet.
Thank you, doctor.

Hello, it doesn't seem like a heart or vascular issue; rather, it appears to be caused by autonomic nervous system dysfunction.
It would be advisable to consult a neurologist for further examination.

More Info


Experiencing chest discomfort and numbness during sleep can be concerning and may indicate underlying health issues that require attention. Based on the symptoms you've described, including a feeling of pressure in the chest, numbness in the tongue, head, and chest, as well as low blood pressure readings and a slow heart rate, several potential causes should be considered.

Firstly, the sensation of pressure in the chest, particularly when lying down, could be related to various factors, including anxiety, positional changes, or even gastroesophageal reflux disease (GERD). When lying flat, some individuals may experience increased pressure in the chest due to the position of the diaphragm and the effects of gravity on the stomach contents. This can lead to discomfort that may feel like pressure or fullness.

The numbness you are experiencing, especially in the tongue and extremities, could be attributed to several factors. One possibility is that it may be related to nerve compression or irritation, which can occur if you are sleeping in a position that puts pressure on certain nerves. For example, sleeping with your arm under your head or body can compress the nerves in your arm, leading to a sensation of numbness or tingling.

Additionally, the combination of low blood pressure (80/56) and a slow heart rate (57 beats per minute) could indicate a condition known as bradycardia, which can lead to insufficient blood flow to the brain and other organs. This may explain the feelings of dizziness and weakness upon waking. It is essential to monitor these symptoms closely, as they could be indicative of an underlying cardiovascular issue or autonomic dysfunction.

Another consideration is the possibility of sleep apnea, a condition characterized by repeated interruptions in breathing during sleep. This can lead to decreased oxygen levels in the blood, resulting in feelings of fatigue, dizziness, and even numbness upon waking. Individuals with sleep apnea often report waking up feeling unrefreshed and may experience symptoms such as loud snoring or gasping for air during sleep.

Given the complexity of your symptoms, it is crucial to seek medical evaluation. A healthcare provider may recommend a thorough assessment, including a physical examination, blood tests, and possibly an electrocardiogram (ECG) to evaluate your heart's rhythm and function. Additionally, a sleep study may be warranted to assess for conditions like sleep apnea.

In the meantime, consider the following strategies to help manage your symptoms:
1. Sleep Position: Experiment with different sleeping positions to see if it alleviates the pressure in your chest and reduces numbness. Elevating your head with pillows may help if GERD is a concern.

2. Stress Management: Since anxiety can exacerbate physical symptoms, incorporating relaxation techniques such as deep breathing, meditation, or gentle yoga before bed may help improve your overall sense of well-being.

3. Hydration and Nutrition: Ensure you are well-hydrated and consuming a balanced diet. Low blood pressure can sometimes be influenced by dehydration or inadequate salt intake.

4. Regular Monitoring: Keep track of your blood pressure and heart rate regularly, especially during episodes of discomfort. This information can be valuable for your healthcare provider.

5. Avoid Stimulants: Limit caffeine and other stimulants, especially in the hours leading up to bedtime, as they can affect your sleep quality and exacerbate anxiety.

In conclusion, while your symptoms may be benign, they warrant further investigation to rule out any serious underlying conditions. Please consult with a healthcare professional for a comprehensive evaluation and tailored management plan. Your health and well-being are paramount, and addressing these symptoms early can lead to better outcomes.
