Dizziness and Lymph Node Issues: A Comprehensive Guide

Dizziness and lymphadenopathy?

Hello doctor, I would like to ask two questions.
I have been experiencing dizziness for a year and a half, feeling dizzy every day, with a tightness and pressure in the back of my head, sometimes accompanied by numbness.
The dizziness feels like a swaying motion, and it is more pronounced when walking or standing, but it lessens when sitting down.
However, I feel completely normal while driving; the dizziness returns as soon as I get out of the car.
I consulted an otolaryngologist, who said this is not the type of dizziness related to ear, nose, and throat issues.
I then saw a neurologist and underwent numerous tests, including a brain CT, brain MRI, neck CT, intracranial blood flow studies, eye movement tests, EEG, tilt table test, autonomic nervous system evaluation, liver and kidney ultrasounds, colonoscopy, blood tests, urine tests, and autoimmune tests, all of which showed no significant issues.
The doctor mentioned that it might be due to anxiety.
Could this be a case of autonomic nervous system dysfunction?
Additionally, three weeks ago, I started feeling tightness in my left jaw, and it feels stiff when I turn my head.
Two weeks ago, I had an ultrasound that revealed a 1.1 cm nodule below the left thyroid gland.
My T3, T4, and TSH levels are normal.
I am scheduled for a fine needle aspiration this week, but prior to the ultrasound, I experienced swelling in my gums, and after feeling unwell, my jaw felt swollen.
Since the thyroid nodule was discovered, I have been feeling more discomfort below my jaw and near my Adam's apple, especially in the last two to three days.
It feels somewhat swollen, and I sometimes experience dull pain below my jaw, as well as occasional dull pain in my left lower teeth, inside my left ear, and below my left earlobe.
Sometimes, I also feel dull pain on the right side of my jaw.
I would like to ask if the area below the jaw is not lymphatic tissue? Why did the lymph nodes not show any swelling, yet I still have these symptoms in my neck? Thank you.

Dr. Zheng Jueyi reply Otolaryngology

Hello, if you have already undergone many examinations for dizziness, it may indeed be related to autonomic nervous system dysfunction.
As for the neck, if an ultrasound has ruled out tumors, the symptoms may be associated with a mild infection.
If there is no improvement, it is advisable to continue follow-up visits.
Wishing you peace and health.
Sincerely, Dr.

More Info

Dizziness and lymph node issues can be complex and multifaceted, often requiring a thorough understanding of both the symptoms and the underlying medical conditions. Based on your description, it seems you are experiencing persistent dizziness, tightness in the back of your head, and discomfort in the area around your jaw and neck, alongside a recently discovered thyroid nodule. Let’s break down these issues and explore potential connections.

Dizziness
Your dizziness, which has persisted for a year and a half, can be attributed to several factors. Given that extensive testing—including CT scans, MRIs, and various blood tests—has not revealed any significant neurological or structural abnormalities, it is plausible that your symptoms may be related to anxiety or a dysfunction in the autonomic nervous system.
Autonomic Nervous System Dysfunction: This system regulates involuntary bodily functions, including heart rate, blood pressure, and digestion. Dysregulation can lead to symptoms such as dizziness, lightheadedness, and a sensation of imbalance. Stress and anxiety can exacerbate these symptoms, creating a cycle that is difficult to break.
Vestibular Disorders: Although your ENT specialist ruled out ear-related causes, vestibular disorders can sometimes manifest with dizziness that is not easily identifiable through standard tests. Conditions like vestibular migraine or benign paroxysmal positional vertigo (BPPV) could be considered, especially if your symptoms are triggered by specific head movements.

Lymph Node and Thyroid Nodule Issues
Regarding the tightness and discomfort in your jaw and neck, as well as the discovery of a thyroid nodule, it is important to consider the anatomy of the area. The submandibular and cervical lymph nodes can become reactive due to various stimuli, including infections or inflammation.
Thyroid Nodules: The presence of a thyroid nodule, especially one that is 1.1 cm in size, warrants further investigation, typically through ultrasound-guided fine needle aspiration (FNA) to rule out malignancy. The fact that your thyroid function tests (T3, T4, TSH) are normal is reassuring, but it does not eliminate the need for follow-up regarding the nodule.

Lymph Node Assessment: You mentioned discomfort in the area where lymph nodes are located, but ultrasound did not reveal any significant enlargement. It is possible for lymph nodes to be reactive without being enlarged enough to be detected on imaging. Inflammation or infection in nearby tissues (like the gums or throat) can also cause discomfort in the lymph node regions without significant enlargement.

Recommendations
1. Follow-Up on Thyroid Nodule: Ensure that you attend your scheduled ultrasound-guided FNA. This is crucial for determining the nature of the nodule and whether any further action is needed.

2. Manage Dizziness: Consider discussing with your healthcare provider the possibility of vestibular rehabilitation therapy or cognitive behavioral therapy (CBT) to address anxiety and its impact on your symptoms.
3. Monitor Symptoms: Keep a detailed log of your symptoms, noting any patterns or triggers. This can be helpful for your healthcare provider in determining the next steps.

4. Dental Evaluation: Given the pain in your teeth and jaw, a dental evaluation may be warranted to rule out any dental issues that could be contributing to your discomfort.

5. Consult a Specialist: If symptoms persist or worsen, consider consulting a neurologist or an otolaryngologist who specializes in dizziness and balance disorders for further evaluation.

In conclusion, while your symptoms may seem interconnected, they can arise from different underlying causes. A multidisciplinary approach involving your primary care physician, endocrinologist, and possibly a neurologist or ENT specialist will be essential in managing your health effectively. Always communicate openly with your healthcare providers about your symptoms and concerns to ensure comprehensive care.
