Do you live in the Tulsa, Oklahoma area and had COVID months ago, or years ago? The infection cleared and something didn’t. You sleep eight hours and wake up depleted. Your thinking is slower than it was. Standing up makes your heart race. You went to your doctor, they ran a panel, and the results came back normal — so you were told there was nothing more to investigate.
That last part is where most people get stuck, and it’s usually where we start.
What long COVID is
Long COVID — also called post-acute sequelae of SARS-CoV-2, or PASC — refers to symptoms that persist or emerge after the acute infection resolves, typically defined as continuing at least twelve weeks. It affects people who were hospitalized and people whose initial illness was mild.
There is no single confirmatory test. Diagnosis rests on history, symptom pattern, and excluding other explanations. That is precisely why standard panels come back unremarkable so often, and why “your labs are normal” is a statement about the labs rather than about you.
Why no two presentations look alike
This is the part that matters most for how you get evaluated, and it’s the part most clinics skip.
Post-COVID presentations are not one condition. Broadly, they cluster:
- Fatigue-dominant — profound exhaustion, post-exertional malaise, crashes that arrive 24–48 hours after activity
- Cognitive-dominant — brain fog, word-finding difficulty, impaired concentration and working memory
- Autonomic — heart rate and blood pressure instability, orthostatic intolerance, temperature and digestive dysregulation
- Inflammatory — joint and muscle pain, new sensitivities, flares of pre-existing conditions
The research literature describes several overlapping biological contributors — immune dysregulation, impaired cellular energy production, persistence or reactivation of viruses including Epstein-Barr, endothelial and microvascular changes, and autonomic nervous system disruption. This is an active and unsettled area of investigation, and different contributors appear to predominate in different people.
The practical consequence: these are not the same problem and should not receive the same workup. A cognitive-dominant presentation and an autonomic-dominant presentation warrant different questions, different testing, and different priorities.
How we evaluate
Your first visit is a long conversation. We want the full timeline — when you were infected, how severe it was, what emerged and when, what has been ruled out already, what you have tried, and what changed when you tried it. That history does more diagnostic work than any single test.
From there, testing is chosen based on your presentation rather than run as a standard panel. Depending on what your history suggests, that may include inflammatory markers, markers relevant to cellular energy metabolism and nutrient status, orthostatic and heart rate variability assessment, thyroid and adrenal evaluation, and viral reactivation panels where the history points that way.
Sometimes testing clarifies the picture. Sometimes it doesn’t, and we will tell you that plainly rather than manufacture an explanation. Where it does help, it informs an individualized plan and a way to track whether anything is actually changing.
Conditions that frequently overlap
A substantial number of people who arrive with post-COVID symptoms turn out to have an overlapping condition that predates or was unmasked by the infection — and that has often never been considered.
We evaluate for and treat:
- POTS and dysautonomia
- Mast cell activation syndrome (MCAS)
- Epstein-Barr virus reactivation
- CIRS and mold-related illness
- Hypermobility spectrum and Ehlers-Danlos presentations
If your symptoms have been attributed entirely to long COVID and one of these is also present, addressing only the first will not get you very far.
What we don’t claim
There is currently no FDA-approved treatment specifically for long COVID. That is true of every clinic, including this one.
The therapies used at Venturis — ozone-based treatments, IV nutrient therapy, photobiomodulation, peptides — are investigational for post-viral presentations. They are not FDA-approved for this purpose, no outcome is promised, and they are considered individually after evaluation rather than applied to a diagnosis off a list.
Anyone telling you they can cure long COVID is ahead of the evidence. Treat that as information about them.
What we do offer is a thorough evaluation, an honest account of what is known and unknown, and a clear answer when we think something else would serve you better.
Practical details
Venturis Clinic is direct-pay and does not bill insurance. We say so in the first conversation rather than after an evaluation is underway, because it is a real tradeoff and you deserve to weigh it with full information.
We are at 7917 N May Ave, Suite B, Oklahoma City, OK 73120, in the Nichols Hills area of north OKC, and we see patients from across the metro — Edmond, Yukon, Moore, Norman, Midwest City — and from elsewhere in Oklahoma.
A free 15-minute phone consultation is available if you want to talk through your situation first. Call (405) 848-7246.
Depending on what your workup shows, one option we may discuss is EBOO therapy for long COVID and Epstein-Barr reactivation. It is not a first step for everyone, and that page states plainly what the evidence does and does not support.
Where to start in Oklahoma — and when to call us
Most people searching for long COVID care in Oklahoma are really asking a simpler question: who is actually doing this here? The answer has changed since 2022, and the pages ranking highest for that question have not kept up.
Two dedicated multidisciplinary post-COVID recovery programmes launched in the Oklahoma City metro in 2021 and 2022, at INTEGRIS Health and at Norman Regional. Both were covered widely at the time. As of this writing neither health system maintains a live page for a dedicated post-COVID programme, and the directory that still ranks at the top of Google for Oklahoma post-COVID care — Survivor Corps’ Post COVID Care Center list — carries a banner stating it has not been updated since March 2023.
We are not saying those programmes are gone; hospital services get folded into other departments all the time, and cardiac and pulmonary rehabilitation remain available. We are saying that if you call based on a 2021 news article or a directory last touched in 2023, you may not find what the page described. Call the health system directly and ask what exists today.
Start with a medical workup if you have not had one
If your symptoms are new, or you have never been properly evaluated, begin with your primary care physician rather than with us. There are findings after COVID that need a physician and sometimes urgent attention — chest pain, significant shortness of breath, syncope, a resting heart rate that has changed materially, new neurological symptoms. Those need cardiology, pulmonology or neurology, not an integrative clinic.
We would rather send you there first than take your money for an evaluation that should have started somewhere else.
When we are the right call
The situation we see most, and the one we are built for, is this:
- You have had the workup. Bloods, imaging, referrals, possibly a specialist or two.
- Everything came back normal, or near enough that no one could act on it.
- You were prescribed something reasonable — for the fatigue, the palpitations, the sleep, the mood — and either it did not change much, or it managed a symptom without touching whatever is generating it.
- You are months or years in, still not yourself, and the medical system has run out of next steps to offer you.
That is not a failure of your doctors. Long COVID has no approved disease-modifying treatment, so the conventional pathway is largely workup plus symptom management, and when the workup is unremarkable there is genuinely little left in that toolkit. It is also precisely the point at which most people stop being investigated — and where a longer history, a differently chosen set of tests, and a look at overlapping conditions like dysautonomia, mast cell activation or viral reactivation sometimes finds something that was never looked for.
Sometimes it does not, and we will say so.
What we are not
We are not a replacement for your physician, and we do not want to be. Dr. Philipose is a Doctor of Chiropractic; we do not prescribe and we do not manage medication.
Do not stop a prescribed medication in order to try something here. If you think something you are taking is not helping, or is causing a problem, that is a conversation with the prescriber — and one we are happy to support with what we find, rather than work around. Several of our patients see us alongside a primary care physician, a cardiologist or a rheumatologist. That is the arrangement we prefer.
If you are still looking for a diagnosis for something that has never been investigated, a medical workup comes first. If you have already been through that and are still unwell, that is when a phone call to us makes sense.
What the evidence actually supports right now
It is worth saying plainly where the science stands, because a lot of what is marketed for long COVID runs ahead of it.
There is, as of today, no approved disease-modifying treatment for long COVID. Nothing reverses it. The large trial programmes running through the NIH RECOVER initiative and elsewhere have produced some signals and a good deal of ambiguity, and several widely promoted interventions have failed to outperform placebo when properly tested.
What does have reasonable support is less dramatic: careful pacing and activity management for people with post-exertional malaise; treating identifiable, treatable overlaps — dysautonomia, mast cell activation, sleep disorders, thyroid disease, nutrient deficiencies, reactivated viral infection; addressing sleep and autonomic regulation directly; and time, which for a meaningful proportion of people does improve things, though rarely in a straight line.
Our integrative options sit alongside that, not instead of it. Where a therapy we offer has thin evidence in long COVID specifically, we say so before you spend money on it rather than after. Patients report benefit from several of them. Reported benefit and demonstrated efficacy are different things, and conflating the two is how this field lost credibility.
What the first few months usually look like
People arrive wanting a timeline. Here is an honest one.
Visit one is history and evaluation. It is long, and it is the part that does most of the diagnostic work. You will not leave with a treatment plan that day if the picture isn’t clear yet.
Weeks two to six are usually testing, if testing is indicated, and the first adjustments — pacing, sleep, whatever the history flagged as most likely to be driving things. Some people notice something in this window. Many do not, and that is not a failure.
Months two to four are where we find out whether the working hypothesis was right. If a treatable overlap was identified and addressed, this is typically when it shows. If nothing has changed at all by this point, that is a signal to revisit the hypothesis rather than to escalate the same approach.
Post-viral illness rarely moves in a straight line. Good weeks followed by a crash are the norm rather than a sign that something has gone wrong. We plan for that pattern instead of being surprised by it.
A word about exercise
This deserves its own heading because getting it wrong causes harm.
If you have post-exertional malaise — a delayed crash 24 to 48 hours after physical or cognitive exertion — then a conventional graded exercise programme can make you materially worse, and there is a well-documented history of people being pushed into exactly that. Screening for post-exertional malaise before recommending any activity increase is not optional, and anyone who prescribes exercise for long COVID without asking about it is not paying attention.
If you do not have post-exertional malaise, careful reconditioning may well be part of your recovery. The distinction matters enormously and it is one of the first things we establish.
Frequently asked questions
Is there a test that confirms long COVID?
No. There is no blood test, scan or biomarker that confirms or excludes it. Diagnosis is clinical — history, symptom pattern, timing relative to infection, and exclusion of other explanations. Any clinic advertising a definitive long COVID test is describing something the field does not have.
My labs came back normal. Does that mean nothing is wrong?
No. It means the panel that was run did not detect an abnormality it was designed to detect. Standard panels are not built to find most of what is proposed to drive post-COVID illness. “Your labs are normal” is a statement about the labs.
Do I need proof of my original infection?
It helps, but it is not required. A great many people were infected during periods when testing was limited, or tested at home and never recorded it. The timeline you can describe is usually more useful than a document.
Can long COVID start months after a mild infection?
Yes. Delayed onset is well described, and severity of the initial illness is a poor predictor of who develops persistent symptoms. Plenty of people who were barely unwell at the time are the ones still affected.
How long does it last?
We don’t know, and we won’t pretend to. Many people improve substantially over months to a couple of years. Some plateau. Some have a relapsing course. Predicting which group you fall into is not currently possible, and a clinician who gives you a confident timeline is guessing.
Should I be exercising?
Only after post-exertional malaise has been screened for. See the section above — this is the question where wrong advice does real damage.
Can children and teenagers develop long COVID?
Yes, though the presentation often differs from adults, with fatigue and cognitive symptoms particularly affecting school performance. We would generally want a paediatrician involved alongside anything we do.
Do you take insurance?
No. We are a direct-pay clinic. You will know what the evaluation costs before you book it, which matters in a condition where people have often already spent a great deal getting nowhere.
Are you a substitute for my regular doctor?
No, and we would rather work alongside them. Dr. Philipose is a Doctor of Chiropractic, not a physician, and we do not prescribe. Where your care needs prescription medication or specialist referral — cardiology for significant autonomic findings, for instance — we will say so and coordinate rather than work around it.
What if long COVID turns out not to be the explanation?
Then that is the finding, and it is worth having. A meaningful number of people who come to us with a post-COVID label have something else going on that has never been properly investigated. Discovering that is a better outcome than treating the wrong thing carefully.
