Nasal allergies


Hello Dr.
Hsiao: For the past month, my son has been constantly sniffing.
One doctor said it is allergies, while another suggested it might be a tic disorder.
We took him to see a pediatric psychiatrist, and the doctor said we need to observe him further.
I would like to know if his symptoms are due to allergies or another condition.
He often complains that his nose is very itchy, but there is no nasal discharge.

Dr. Xiao Kaiwen reply Pediatrics


Nasal itching, nasal congestion, sneezing, and persistent runny nose are most likely due to nasal allergies in Taiwan.
If there is a family history of allergies (such as allergic rhinitis, asthma, or skin allergies), the likelihood increases.
Blood tests can be conducted to measure allergy levels and identify allergens for reference.
Other possible causes include sinusitis (characterized by prolonged yellow or purulent nasal discharge or postnasal drip), foreign bodies in the nasal cavity (especially if there is unilateral nasal congestion and discharge), nasal polyps, turbinate hypertrophy, deviated septum, and neurological conditions such as tic disorders.

More Info


Understanding the distinction between allergies and tic disorders in children can be quite challenging for parents, especially when symptoms overlap. In your case, your son has been experiencing nasal symptoms, including frequent nose rubbing and itchiness, which have led to a diagnosis of allergies by one doctor, while another suggested the possibility of a tic disorder. This situation can understandably cause confusion and concern.


Allergies in Children
Allergies are a common issue in children and can manifest in various ways, including nasal congestion, sneezing, itchy eyes, and runny or stuffy noses. Allergic rhinitis, often referred to as hay fever, is particularly prevalent and can be triggered by environmental allergens such as pollen, dust mites, pet dander, or mold. The symptoms you describe—itchy nose and the sensation of needing to clear the nose without much nasal discharge—are consistent with allergic rhinitis.
When a child has allergies, the immune system overreacts to harmless substances, leading to inflammation in the nasal passages. This inflammation can cause the nasal mucosa to swell, resulting in a blocked or itchy nose. In some cases, children may not produce a significant amount of mucus, which could explain why your son feels the need to clear his nose but does not have a runny nose.


Tic Disorders
On the other hand, tic disorders are characterized by sudden, repetitive movements or sounds that are difficult to control. Tics can be motor (such as blinking, head jerking, or nose rubbing) or vocal (such as throat clearing or grunting). The presence of tics can sometimes be mistaken for habitual behaviors or responses to discomfort, such as itching from allergies.
In your son's case, if the nose rubbing is a tic rather than a response to an allergic reaction, it may be accompanied by other motor or vocal tics. Tic disorders can vary in severity and may be transient or chronic. They often become more noticeable during periods of stress or excitement.


Next Steps
Given the complexity of your son's symptoms, it is crucial to continue monitoring his condition. Here are some steps you can take:
1. Consultation with Specialists: Since you have already seen a pediatric mental health specialist, it may be beneficial to follow up with an allergist or an ear, nose, and throat (ENT) specialist. They can conduct specific tests, such as skin prick tests or blood tests, to identify potential allergens.

2. Symptom Diary: Keep a diary of your son's symptoms, noting when they occur, their severity, and any potential triggers (such as exposure to pets, dust, or pollen). This information can be valuable for healthcare providers in making an accurate diagnosis.

3. Environmental Control: If allergies are confirmed, consider implementing strategies to reduce exposure to allergens. This may include using air purifiers, keeping windows closed during high pollen seasons, and regularly cleaning your home to minimize dust and pet dander.

4. Behavioral Observation: If tics are suspected, observe whether your son exhibits other tics or if the nose rubbing occurs in specific situations (e.g., during stress or excitement). This can help differentiate between a tic disorder and an allergic response.

5. Follow-Up Appointments: Regular follow-ups with your healthcare providers are essential. If symptoms persist or worsen, further evaluation may be necessary to adjust treatment plans accordingly.


Conclusion
In summary, distinguishing between allergies and tic disorders in children requires careful observation and sometimes a multidisciplinary approach. By consulting with specialists, maintaining a symptom diary, and implementing environmental controls, you can better understand your son's condition and provide him with the appropriate support. Remember, it’s essential to communicate openly with your healthcare providers about your concerns and observations to ensure your son receives the best possible care.
