Long COVID Diagnosis & Treatment in Portland, Oregon
Compassionate, Comprehensive Care for Longhaul Syndrome & Post-Viral Illness
Dr. Cori Burkes provide comprehensive evaluation and treatment of Long COVID Syndrome in Portland, Oregon. Many people experience lingering symptoms after COVID-19 infections and they spend months or even years searching for answers while struggling with fatigue, brain fog, dizziness, pain, sleep disruption, and worsening quality of life. If you’ve never fully recovered after a COVID-19 infection, you deserve answers, not dismissal. Long COVID can be complex, but it’s also treatable.
At Willow Natural Health, Dr. Burke specializes in helping patients in Portland, Milwaukie, and surrounding Oregon communities navigate complex chronic illness, including Long COVID and post-viral syndromes. She is an expert at untangling the underlying mechanisms driving your symptoms and building a path toward genuine recovery.
What is Long COVID?
Long COVID, also called Post-Acute Sequelae of SARS-CoV-2 (PASC), occurs when symptoms continue, fluctuate, or newly emerge weeks to months after an initial COVID-19 infection — regardless of how mild or severe that infection was.
Some people recover quickly from COVID-19, while others develop persistent symptoms that significantly impact daily functioning, work, cognition, physical activity, and emotional well-being.
Long COVID can affect multiple body systems simultaneously, including the nervous system, immune system, cardiovascular system, gastrointestinal tract, respiratory system, and brain.
Symptoms of Long COVID
Long COVID symptoms can vary widely from person to person and often fluctuate over time. Common symptoms may include:
- Chronic fatigue and post-exertional malaise
- Brain fog and cognitive dysfunction
- Dizziness, lightheadedness, or fainting
- POTS and dysautonomia
- Shortness of breath or chest discomfort
- Heart palpitations and exercise intolerance
- Sleep disturbances and unrefreshing sleep
- Headaches and migraines
- Muscle and joint pain
- Gastrointestinal symptoms including nausea, bloating, IBS, and SIBO
- Histamine intolerance and Mast Cell Activation Syndrome (MCAS) symptoms
- Sensory sensitivity and nervous system dysregulation
- Anxiety, mood changes, or overstimulation related to autonomic dysfunction
- Persistent inflammation and immune dysregulation
Many patients with Long COVID also develop overlapping conditions such as ME/CFS, dysautonomia, MCAS, hypermobility-related symptoms, or chronic neuroinflammatory patterns.
Causes of Long COVID
The causes of Post-Acute Sequelae of SARS-CoV-2 (PASC) are not fully understood and they likely differ from person to person. Research points to several potential overlapping mechanisms including immune dysregulation, reactivation of latent viruses, mitochondrial dysfunction, mast cell activation, and autonomic nervous system dysfunction. For most people with Long COVID, it isn’t just one of these factors, but a combination of them that causes a variety of lingering, persistent symptoms.
Comprehensive Diagnostic Evaluation for Post-Acute Sequelae of SARS-CoV-2
There is no single definitive test for Long COVID, therefore diagnosis is clinical, informed by your history, symptom pattern, and ruling out other potential explanations for your symptoms. At Willow Natural Health evaluation for Long COVID is designed to identify the specific factors contributing to your symptoms so that you can receive a focused plan for healing.
An Individualized Recovery Plan
Because Long COVID affects multiple systems simultaneously, treatment must be equally multi-dimensional. Dr. Burke prioritizes the most impactful interventions first, layering in additional support over time. Treatment is individualized and based on your symptoms, functional capacity, and underlying contributors.
Dr. Burke’s goal is to help stabilize the nervous system, reduce inflammation, balance the immune response, improve resilience, and support you on your journey to full recovery.
“Recovery from Long COVID isn’t linear, but with the right support and the right pacing, most people do improve. I’m honored to be here for the whole journey.”
