The body feels tense and warm?


Hello, Doctor: Recently, I have been feeling tightness in my shoulders and neck, and sometimes I also feel tightness in my right ear.
I have been experiencing nerve pain, with occasional tingling in my calves and near my toes.
My body feels warm, including my limbs, back, and lower back, but I do not have a fever when measuring my temperature.
Additionally, my eyes sometimes flicker, and I feel like my focus is unclear.
I have seen an ophthalmologist, who found no significant issues.
Recently, my blood pressure readings have fluctuated quite a bit; the first reading was about 124, and the second was about 116, with similar readings occurring two or three times.
Since June, I have been experiencing intermittent gastroesophageal reflux.
Could this be a case of autonomic nervous system dysregulation? What could be the underlying causes?

Dear Ms.
Deddy,
You mentioned "autonomic nervous system dysfunction," a term that is widely used because it is important to identify the underlying causes of this phenomenon.
Generally, the autonomic nervous system is regulated by the sympathetic and parasympathetic nervous systems—one acts as the accelerator, while the other serves as the brake.
The sympathetic nervous system is responsible for stimulating the "gas pedal," driving the body into action, while the parasympathetic nervous system is responsible for applying the "brakes," allowing the body to rest.

For example, during exercise, the sympathetic nervous system is activated, leading to increased heart rate, faster breathing, and increased sweating.
Once the exercise stops, the parasympathetic nervous system takes over, slowing the heart rate, reducing breathing speed, and decreasing sweating.

You mentioned experiencing "significant fluctuations in blood pressure and gastroesophageal reflux," which may suggest symptoms of sympathetic nervous system overactivation.
The sensation of "eyes occasionally flickering, as if not focusing clearly" could be indicative of a prodromal migraine.
The occasional "tingling in the calves and toes" may warrant consideration of lumbar nerve root or peripheral nerve pathology.

I recommend consulting a neurologist for discussion and treatment.
However, given the variety of symptoms, it may take some time for the physician to clarify the underlying causes of your condition and assess treatment outcomes.
Please ensure to practice self-protection, maintain cleanliness and disinfection, and adhere to new preventive health measures before and after your medical visits.
Thank you for your inquiry.
If you have further questions, feel free to discuss them!
Wishing you good health, peace, and joy.
Dr.

More Info


Hello! Thank you for sharing your symptoms and concerns. Based on what you've described, it does seem like you may be experiencing symptoms related to autonomic nervous system (ANS) dysfunction. The ANS is responsible for regulating involuntary bodily functions, including heart rate, blood pressure, digestion, and respiratory rate. When the ANS is not functioning properly, it can lead to a variety of symptoms, which you seem to be experiencing.


Symptoms and Their Possible Connections to Autonomic Nervous System Dysfunction
1. Muscle Tension and Pain: The tightness in your neck and shoulders could be a result of muscle tension, which is often exacerbated by stress and anxiety. This tension can also lead to referred pain, which may explain the discomfort you feel in your right ear and the nerve pain in your legs.

2. Numbness and Tingling: The occasional numbness in your lower legs and toes could be related to nerve compression or irritation, which can occur due to muscle tension or poor posture. However, it can also be a symptom of autonomic dysfunction, particularly if there are accompanying symptoms like heat sensations.

3. Temperature Regulation Issues: Feeling hot in various parts of your body, including your limbs and back, without an actual fever, can indicate dysregulation of the autonomic nervous system. The ANS plays a crucial role in thermoregulation, and dysfunction can lead to abnormal sensations of heat or cold.

4. Visual Disturbances: The flickering or unclear vision you mentioned could be linked to autonomic dysfunction as well. The ANS affects the muscles that control pupil dilation and constriction, which can impact your ability to focus.

5. Blood Pressure Variability: The fluctuations in your blood pressure readings (124/116 mmHg) suggest that your body may be struggling to maintain stable cardiovascular function, which is another hallmark of autonomic dysfunction. This can lead to symptoms like dizziness or lightheadedness, especially when changing positions.

6. Gastroesophageal Reflux Disease (GERD): The intermittent episodes of gastroesophageal reflux could also be related to autonomic dysfunction. The ANS regulates the lower esophageal sphincter, and dysfunction can lead to improper closure, resulting in reflux symptoms.


Potential Causes of Autonomic Nervous System Dysfunction
Several factors can contribute to autonomic dysfunction, including:
- Stress and Anxiety: Chronic stress can lead to heightened sympathetic nervous system activity, which may manifest as muscle tension, increased heart rate, and digestive issues.


- Postural Issues: Poor posture can lead to muscle imbalances and nerve compression, contributing to symptoms like pain and numbness.

- Dehydration or Electrolyte Imbalance: Insufficient hydration or imbalances in electrolytes can affect blood pressure and overall autonomic function.

- Medical Conditions: Conditions such as diabetes, multiple sclerosis, or autoimmune disorders can also affect the ANS.


Recommendations
1. Consult a Specialist: It may be beneficial to consult with a neurologist or a specialist in autonomic disorders. They can perform specific tests to assess your autonomic function and rule out other potential causes.

2. Lifestyle Modifications: Incorporating stress management techniques such as mindfulness, yoga, or physical therapy may help alleviate muscle tension and improve overall well-being.

3. Hydration and Nutrition: Ensure you are well-hydrated and consider a balanced diet rich in electrolytes, which can support nerve and muscle function.

4. Monitor Symptoms: Keep a detailed log of your symptoms, including their frequency, duration, and any potential triggers. This information can be valuable for your healthcare provider in diagnosing and managing your condition.

5. Follow-Up on Blood Pressure: Regularly monitor your blood pressure and discuss any significant fluctuations with your healthcare provider.

In conclusion, your symptoms do suggest a possible dysfunction of the autonomic nervous system, and addressing them with a healthcare professional will be crucial for proper diagnosis and management. Please take care, and I hope you find relief soon!
