Sinus and nasal symptoms that keep returning
Sinus and nasal symptoms that keep returning usually have one of three causes: an allergic driver, a structural problem, or chronic inflammation that has become self-sustaining. Frequently more than one is present at once. The evaluation at Allergenix establishes which applies to you, because the treatment that works for one does very little for the others.
Congestion that never fully clears is worth a proper evaluation, not another round of the same treatment.

Does any of this sound like your sinuses?
- Sinus infections that keep coming back
- Congestion that is there most of the year rather than seasonally
- Post-nasal drip, throat clearing or a cough that will not settle
- Treatments that help for a while and then stop working
What a sinus and nasal evaluation can involve
Allergic or structural
The first question is which one you are dealing with, because a structural cause will not respond to allergy treatment however long you continue it.
Testing in the clinic
Skin testing evaluation during the visit so an allergic driver is confirmed or ruled out the same day.
Chronic sinusitis
Recurring infections evaluated properly rather than treated one course at a time. We may order CT imaging to further identify problems with anatomy.
A written plan
Including, where the cause turns out to be structural, what kind of specialist should see it next.

Allergic, structural, or both
Three things cause most persistent nasal and sinus symptoms, and telling them apart determines what will actually help.
- Allergic
- Driven by an immune response to something you breathe in — pollen, dust mites, mold, animal dander. It tends to come with itching and sneezing alongside congestion, and it responds to allergen avoidance, nasal steroids, antihistamines and immunotherapy.
- Structural
- A deviated septum, enlarged turbinates, nasal polyps, or in children enlarged adenoids. Congestion is often worse on one side, or constant regardless of season. Allergy treatment will not resolve it, however long it continues — this is the group that has usually been on nasal sprays for years without benefit.
- Chronic inflammation without an allergic driver
- Chronic rhinosinusitis, with or without polyps, and non-allergic rhinitis triggered by temperature changes, strong smells or weather. The symptoms look similar and the testing is negative.
The complication is that these overlap constantly. Someone with a deviated septum can also have dust mite allergy, and treating one while ignoring the other produces a partial result that gets read as treatment failure. The evaluation here establishes what is present, in what proportion — and where a structural problem is the dominant issue, we say so and refer to ENT rather than continuing to treat around it.

When it is worth seeing ENT instead
Being direct about this is more useful than keeping every patient in the building.
Start with an allergist if
- Symptoms follow a seasonal pattern
- Itching and sneezing are prominent
- Symptoms improve away from home, or worsen around animals
- You also have asthma or eczema
- You have been on nasal steroids for months without a clear diagnosis
See an ENT surgeon first if
- Your congestion has always been one-sided
- You have had a facial injury affecting your nose
- You have lost your sense of smell for an extended period
- You have had recurrent nosebleeds
- Imaging has already shown polyps or a significantly deviated septum
Where both are involved — and they often are — the two work in parallel. Surgery on a structural problem tends to hold up considerably better when the allergic component is treated as well.

Children, mouth breathing and sleep
In children, persistent nasal blockage is worth taking seriously for a reason beyond the congestion itself.
A child showing these signs may be experiencing sleep-disordered breathing.
At night
- Breathes through their mouth most of the time
- Snores regularly
- Sleeps restlessly
- Wakes unrefreshed
During the day
- Irritability
- Difficulty concentrating
- Behavior that gets attributed to something else entirely
- Often not obvious sleepiness
The common causes are enlarged adenoids and tonsils, allergic rhinitis, or both together. Establishing which is present matters, because the treatments are different and because allergic inflammation that is treated properly can meaningfully reduce the obstruction. Where adenoid or tonsil size is the dominant factor, that is an ENT conversation and we will say so.
Every fee is published before you book — what testing costs sets out the figures for this. When the answer turns out to be a program rather than a prescription, four different immunotherapy treatments become options to assist your symptoms. What a first visit involves walks through the visit itself, and Dr. Stanga runs all of it — the evaluation, the testing and the plan.
WHAT YOU LEAVE WITH
A clear answer on whether what you have is allergic or structural — and a plan that follows from the answer rather than preceding it.
Questions about sinus and nasal symptoms
How do I know if my congestion is allergic or structural?
Some signals point one way — seasonal timing, itching and sneezing, and improvement away from home suggest allergy, while constant one-sided blockage suggests structure. But the two overlap often enough that testing is what settles it. That is a single visit here, with results the same day.
I have been on a nasal steroid spray for years and it barely helps. Why?
A few possibilities: the cause may be structural rather than allergic, the spray may be being used incorrectly, which is very common, or there may be an allergic driver that has never been identified and removed. All three are worth checking before adding another medication.
Can allergy treatment help chronic sinus infections?
Where an allergic driver is present, yes — treating it reduces the inflammation that keeps sinuses obstructed and infected. Where the cause is structural or the sinuses are already chronically diseased, allergy treatment alone will not be enough, and that is worth knowing early rather than after another year.
Do you treat nasal polyps?
Polyps are evaluated here, and the biologic therapies approved for chronic rhinosinusitis with nasal polyps — dupilumab among them — are administered here. Where polyps are extensive enough to need surgical management, that is an ENT referral, and the two are often combined.
My child snores and breathes through their mouth. Is that an allergy problem?
It can be, and it can also be enlarged adenoids or tonsils, or both together. It is worth evaluating either way, because persistent mouth breathing and disrupted sleep in children affect more than their nose.
Do I need a referral to be seen?
No. No referral, no prior authorization, and no insurance involved.
