Inquiry related to symptoms of autonomic nervous system dysfunction?


Hello, doctor.
I was hospitalized for a month two months ago due to bone marrow suppression caused by medication side effects.
After my blood cell counts improved, I was discharged.
However, half a month after discharge, I began to feel a persistent sensation of not being able to take a full breath.
I also noticed lymph nodes swelling in my neck and armpits, which made me anxious about possibly having lymphoma.
I went to see a hematologist, and after X-rays and blood tests, everything appeared normal, and the doctor said they couldn't feel any lumps.
However, I am certain that I can feel them.
Despite seeing the doctor, I still can't shake off my anxiety.
The doctor mentioned that this might be due to anxiety after my hospitalization leading to autonomic nervous system dysregulation.
However, aside from the breathing difficulty, I do not have other symptoms related to autonomic nervous system dysregulation.
My breathing difficulty is alleviated when lying down (especially on my side), and I can breathe normally while sleeping and just after waking up.
However, after noon, I gradually feel the sensation of not being able to take a full breath until bedtime.
I do not feel any foreign body sensation in my throat, nor do I have a cough or nasal congestion; I just feel like I have to exert more effort to breathe in.
My heart rate has been consistently elevated, around 90 at rest and over 100 when walking, but I do not feel palpitations.
I have a history of asthma in elementary school, but it has not flared up for several years.
I also have a hunchback and mild scoliosis.
I would like to ask the doctor:
1.
Is this truly anxiety causing autonomic nervous system dysregulation? Because I did not have breathing difficulties during my hospitalization; they only started after my recovery.
2.
Can patients with autonomic nervous system dysregulation experience a sensation of not being able to take a full breath for several consecutive days? I have been experiencing this for three weeks now, and I thought that autonomic nervous system dysregulation would only cause breathing difficulties during episodes, while I could breathe normally otherwise.
3.
Is it possible for breathing difficulties caused by autonomic nervous system dysregulation to be alleviated by lying down? Or could there be another underlying issue with my breathing difficulties?
4.
Can autonomic nervous system dysregulation worsen premenstrual syndrome (PMS)? I feel that since I started experiencing breathing difficulties, my breasts have become more swollen and painful before my period, but they return to normal after menstruation.
5.
How long does it typically take for symptoms of autonomic nervous system dysregulation to improve without medication?
Thank you, doctor, for taking the time to respond.

Hello: Autonomic nervous system dysfunction is merely a syndrome and not a diagnosis.
It is important to identify the underlying causes of your autonomic dysfunction, which may include health anxiety, physical discomfort, environmental factors, or psychological stress.
It is recommended that you visit a nearby psychosomatic medicine clinic for an in-person consultation with a physician who can assess your condition and conduct more comprehensive examinations.
I hope this answers your question :)

Understanding autonomic nervous system (ANS) disorders is crucial, especially when symptoms like difficulty breathing, anxiety, and other physical manifestations arise. Based on your description, it seems you are experiencing a complex interplay of symptoms that may indeed be related to autonomic nervous system dysregulation, particularly following your recent hospitalization and the associated stress.

1. Is your condition truly due to anxiety-induced autonomic nervous system dysregulation?
It is quite possible. The stress of hospitalization, combined with the fear of serious health issues (like lymphatic cancer), can trigger anxiety responses that affect the autonomic nervous system. This system controls involuntary bodily functions, including heart rate and respiratory patterns. Your experience of difficulty breathing, particularly when lying down, could be a manifestation of anxiety rather than a direct physiological issue, especially since you did not experience these symptoms during your hospitalization.

2. Can autonomic nervous system dysregulation cause prolonged feelings of breathlessness?
Yes, it can. Individuals with ANS disorders may experience persistent sensations of breathlessness or difficulty in taking deep breaths, often exacerbated by anxiety. This can happen even when there are no underlying respiratory issues. The sensation of needing to exert more effort to breathe can be distressing and may lead to a cycle of anxiety, further complicating the situation.

3. Is it possible for breathing difficulties caused by autonomic nervous system dysregulation to improve when lying down?
Yes, many individuals report that their symptoms improve in certain positions, such as lying down. This could be due to a variety of factors, including the relaxation of the body in a horizontal position, which may alleviate some of the tension associated with anxiety. However, it is essential to monitor these symptoms closely, as they could also indicate other underlying issues that may require further investigation.

4. Can autonomic nervous system dysregulation exacerbate premenstrual syndrome (PMS) symptoms?
Yes, there is evidence to suggest that stress and anxiety can worsen PMS symptoms. The autonomic nervous system plays a role in regulating hormonal balance, and dysregulation can lead to increased sensitivity to hormonal fluctuations, resulting in more pronounced symptoms like breast tenderness and mood swings.

5. How long might it take for symptoms of autonomic nervous system dysregulation to improve without medication?
The timeline for symptom relief can vary significantly from person to person. Some individuals may notice improvement within a few weeks of implementing lifestyle changes, such as stress management techniques, regular exercise, and adequate sleep. Others may require a longer period to see significant changes. It is important to work closely with your healthcare provider to develop a tailored approach that may include therapy, lifestyle modifications, and possibly medication if necessary.

In summary, your symptoms could very well be linked to autonomic nervous system dysregulation, particularly in the context of anxiety following your hospitalization. It is essential to continue working with your healthcare providers to explore these symptoms further, ensuring that any potential underlying conditions are ruled out while also addressing the psychological aspects of your experience. Techniques such as cognitive-behavioral therapy (CBT), mindfulness, and relaxation exercises can be beneficial in managing anxiety and its physical manifestations. If symptoms persist or worsen, further evaluation may be warranted to ensure comprehensive care.
