Maybe it started with a tick bite on a hike near Horsetooth Reservoir, a rough case of mono back in college, or a bout of COVID that never quite resolved. Months later, you're still dealing with fatigue that sleep doesn't fix, brain fog that makes work harder than it used to be, joint aches that come and go, or a low-grade sense that something in your body isn't running the way it should. You've had bloodwork done. Your primary care provider says your labs look normal. So why do you still feel this way?
If that sounds familiar, you're not alone, and you're not imagining it. Many people in Fort Collins and across Northern Colorado come to Nomadic Naturopathic Solutions after months, sometimes years, of unexplained symptoms, wondering whether a chronic or lingering infection could be part of the picture. A chronic infection evaluation with Dr. Danny Dowling, ND, is built around looking at your health history as a whole, and considering possibilities that a fifteen-minute conventional visit may not have had time to explore.
What a Chronic Infection Evaluation in Fort Collins May Involve
A chronic infection evaluation is not a single test or a same-day diagnosis, it's a process. When you sit down with Dr. Danny, the visit typically starts with an extended conversation: when your symptoms began, what was happening in your life and health around that time, what you have already tried, and what conventional testing has and has not shown. From there, he may recommend specific categories of lab work to help clarify the picture, along with nutrition, lifestyle, and immune-support strategies tailored to what your history suggests. You can read more about how initial and follow-up visits typically unfold on our What to Expect page.
Because chronic and lingering infections can touch so many body systems, immune, nervous, hormonal, and digestive among them, evaluation is rarely a single appointment. Most patients work with Dr. Danny over a series of visits, refining the picture as test results come back and as your body responds to initial changes in nutrition, sleep, stress management, or targeted support.
It's also worth remembering that a chronic infection evaluation is meant to work alongside your existing medical care, not in place of it. If you are already seeing a primary care provider, infectious disease specialist, rheumatologist, or other clinician, Dr. Danny's goal is to add a root-cause, whole-person perspective to that care, not to replace any prescribed treatment or ongoing monitoring you already have in place.
Common Patterns We See in Chronic and Lingering Infections
Every patient's story is different, but a few patterns come up often among people dealing with lingering illness in our Fort Collins practice. What follows is a brief overview, not a complete picture. For a deeper look at how these conditions relate to one another, see our full guide.
Lyme Disease and Tick-Borne Exposure
Lyme disease is caused by Borrelia bacteria spread through the bite of an infected blacklegged tick, according to the CDC. Colorado's tick population is dominated by species such as the Rocky Mountain wood tick and the American dog tick rather than the blacklegged tick that spreads Lyme, so it is not generally considered a locally endemic risk here in Larimer County. Even so, we see patients in Fort Collins who were bitten while traveling, who spent time in other regions before moving here, or who never fully resolved symptoms that began after a tick bite years ago. Diagnosis can be tricky: CDC-recommended two-tier antibody testing tends to work best several weeks after exposure, and antibodies can persist long after an infection has cleared, so a single positive or negative result doesn't always tell the whole story.
EBV and Mono Reactivation
Epstein-Barr virus, the virus responsible for infectious mononucleosis, infects most people at some point in life and then remains dormant in the body indefinitely, according to the CDC. For most people, it stays quiet permanently. Researchers are still studying whether EBV reactivation contributes to prolonged fatigue and immune symptoms in a subset of patients, and this remains an active area of investigation rather than settled science. If you had mono in the past and never quite felt like yourself again afterward, it may be worth discussing.
Post-Viral Syndrome
Post-viral syndrome refers to symptoms, fatigue, brain fog, exercise intolerance, and sleep disruption among them, that persist for weeks or months after an acute infection has otherwise resolved. Ongoing NIH research into long COVID, including through NIAID and the RECOVER initiative, has brought new attention to this general pattern, though the underlying mechanisms are still being worked out. Post-viral symptoms aren't limited to COVID-19; we also see them following flu, mono, and other common infections. If this pattern sounds familiar, our related article goes deeper into what may be happening.
Mold-Related Illness
Mold exposure and its potential connection to chronic symptoms is a genuinely debated area of medicine. Some patients report fatigue, sinus congestion, brain fog, or other symptoms that seem to track with time spent in a water-damaged building, and some clinicians use frameworks such as Chronic Inflammatory Response Syndrome, or CIRS, to describe this. However, the diagnostic criteria and treatment approaches associated with CIRS are not universally accepted in mainstream medicine, and research in this area is still developing. If you suspect mold may be a factor in your health, we approach it as one possibility worth exploring carefully, not an automatic conclusion.
Recurring Infections and Immune Dysfunction
Some patients simply seem to catch every cold, sinus infection, or bladder infection that comes around, or notice that minor illnesses take far longer to resolve than they used to. This pattern can sometimes point toward underlying immune dysfunction, nutrient depletion, chronic stress, or other factors that make it harder for the body to mount and complete a normal immune response.
Possible Contributing Factors Worth Exploring
Chronic and lingering infections rarely exist in isolation. Several factors may make it harder for your body to fully recover, or may overlap with infection-related symptoms, including:
Chronic, unmanaged stress and disruption of the body's stress-response system
Nutrient depletion, such as low iron, vitamin D, or B12
Poor sleep quality or ongoing circadian disruption
Gut health and microbiome imbalances
Environmental exposures, including mold or other toxins
Autoimmune or rheumatological overlap
Prior significant illness that was never fully resolved
Because autoimmune and infection-related symptoms can overlap significantly, some patients also find it helpful to read about AutoImmune & Rheumatological Triggers and Areas of Treatment, since immune dysregulation is sometimes a shared thread between the two.
What We Consider During an Evaluation: History, Timeline, and Testing
Dr. Danny takes time to build a full timeline with you: when symptoms began, what happened around that time, such as an illness, travel, a tick exposure, water damage at a home or workplace, or a period of major stress, how your symptoms have evolved since, and what has already been ruled out. Depending on your history, he may discuss testing categories such as:
Complete blood count and general inflammatory markers
Thyroid and hormone panels
Nutrient and vitamin levels
Infection-specific antibody or antigen testing, when clinically appropriate
Markers related to immune function
No single test can identify every possible cause of chronic symptoms, and testing decisions are based on your individual history and presentation rather than run as a blanket panel for every patient.
Practical Information to Track Before Your Appointment
Before your appointment, it can help to gather a few things so your visit can be as productive as possible:
A timeline of your symptoms, including when they started and how they have changed
Any known tick bites, a history of mono or EBV illness, or other significant past infections
Any history of water damage, visible mold, or musty odors in homes or workplaces you have lived or worked in
Copies of recent lab results, even ones you were told were normal
A current list of medications and supplements
Family history of autoimmune or chronic illness
Notes on what makes your symptoms better or worse, such as exertion, stress, or time of day
When Professional Evaluation May Be Appropriate
If you have been dealing with unexplained fatigue, recurring illness, or lingering symptoms for more than a few weeks after what should have been a full recovery, and your primary care workup hasn't turned up clear answers, a chronic infection evaluation may be a helpful next step. This is especially true if the symptoms are affecting your work, relationships, or day-to-day quality of life, or if you have a history of tick exposure, mono, a significant illness, or mold exposure that lines up with when your symptoms began.
Red Flags That Call for Urgent Conventional Care
Naturopathic evaluation is not appropriate for emergency situations. Please seek immediate or conventional medical care for:
A tick bite followed by an expanding red rash, especially a bull's-eye pattern, along with fever or facial drooping
High fever, a severe headache, a stiff neck, or confusion
Chest pain, difficulty breathing, or a rapid or irregular heartbeat
Sudden or severe joint swelling
Signs of a serious or worsening infection, such as spreading redness, high fever, or feeling seriously unwell
Any new neurological symptoms, such as numbness, weakness, or vision changes
If you experience any of these, please contact your primary care provider, an urgent care clinic, or emergency services right away. Naturopathic care is meant to complement conventional medical evaluation, not replace it, especially for acute or urgent concerns.
Why Local, In-Person Root-Cause Care in Fort Collins May Help
There is real value in working with a clinician who can see you in person, over time, in the community where you live. Local factors, Colorado's altitude, dry climate, seasonal allergens, and regional tick and mold exposures, can all be part of your health picture, and an ongoing in-person relationship allows for the kind of conversation that chronic symptoms often require. At Nomadic Naturopathic Solutions, Dr. Danny works with patients throughout Fort Collins and Northern Colorado to build a full picture of their health history and explore root-cause possibilities together.

Frequently Asked Questions
How do I know if I need to see a naturopath for chronic infections in Fort Collins?
If you've had unexplained fatigue, brain fog, recurring illness, or lingering symptoms for weeks or months after what should have been a full recovery, and conventional testing hasn't provided clear answers, a chronic infection evaluation may be worth considering. It's not a substitute for care from your primary provider or a specialist, but it can add a whole-person, root-cause perspective to what you've already been through.
Can testing definitively diagnose Lyme disease, EBV reactivation, or mold illness?
No single test can identify every possible cause of chronic symptoms. Lyme disease testing, for example, works best within a specific window after exposure and can remain positive long after an infection has cleared. EBV reactivation and mold-related illness are still active areas of research without one definitive diagnostic test. Evaluation typically involves combining your history and timeline with several testing categories, rather than relying on a single result.
Do you serve patients outside of Fort Collins in Northern Colorado?
Yes. While Nomadic Naturopathic Solutions is based in Fort Collins, we regularly work with patients from across Northern Colorado, including surrounding communities in Larimer and Weld counties, who are looking for an in-person, root-cause approach to chronic and lingering infection concerns.
Will I need to stop medications my doctor has prescribed?
No. A chronic infection evaluation is meant to work alongside your existing medical care, not replace it. Dr. Danny will not ask you to discontinue medications or treatments prescribed by another provider; any changes to prescribed care should always be discussed directly with the prescribing clinician.
Is mold-related illness a widely accepted diagnosis?
It's genuinely debated. Some patients and clinicians describe a pattern of symptoms connected to water-damaged buildings using frameworks like Chronic Inflammatory Response Syndrome (CIRS), but the diagnostic criteria and treatment approaches are not universally accepted in mainstream medicine, and research is still evolving. We treat it as one possible factor to explore carefully, not an automatic conclusion.
