Allergies: Symptoms and Management in a New Environment - Pulmonology

More Info

---

It sounds like you are experiencing a range of allergic reactions, particularly after moving to a new environment in Japan. Your symptoms, including itchy skin, nasal congestion, throat irritation, and difficulty breathing deeply, suggest that you may be dealing with multiple allergens. Given your history of allergic rhinitis and dermatitis, it is not uncommon for these conditions to be exacerbated by new environmental factors, such as pollen, pet dander, and certain foods.


Understanding Your Symptoms
1. Allergic Reactions: The itchy bumps on your hands after consuming shellfish and fish roe indicate a possible food allergy. Allergies can develop at any age, even if you have previously consumed these foods without issue. The symptoms you describe, such as itchy eyes, runny nose, and throat irritation, are classic signs of allergic rhinitis, often triggered by pollen during the spring season.

2. Respiratory Symptoms: The sensation of tightness in your throat and difficulty taking deep breaths could be related to your allergies. While you mentioned you do not have asthma, the presence of wheezing sounds when breathing through your mouth can be concerning. Allergic reactions can sometimes lead to bronchoconstriction, which may mimic asthma symptoms, even in individuals who have not been previously diagnosed.

3. Pet Allergies: Living with a large dog can significantly impact your allergic responses, especially if you are sensitive to pet dander. The constant exposure to the dog's fur and dander can lead to persistent symptoms, including itchy skin and respiratory discomfort.


Management Strategies
1. Avoidance: The most effective way to manage allergies is to avoid known triggers. While it may not be feasible to remove the dog from your home, you can take steps to minimize exposure. Consider designating pet-free zones in your living space, particularly in your bedroom, and use air purifiers to help reduce airborne allergens.

2. Medication: Over-the-counter antihistamines can help alleviate symptoms such as itching, nasal congestion, and throat irritation. Nasal corticosteroids may also be beneficial for managing allergic rhinitis. If your symptoms persist or worsen, consult with a healthcare provider for a tailored treatment plan, which may include prescription medications.

3. Allergy Testing: Since you are experiencing new symptoms, it may be worthwhile to undergo allergy testing. This can help identify specific allergens that are triggering your reactions, allowing for more targeted management strategies.

4. Environmental Control: Regular cleaning can help reduce allergens in your home. Vacuuming with a HEPA filter, washing bedding frequently, and using dust mite-proof covers on pillows and mattresses can make a significant difference. Additionally, during pollen season, keeping windows closed and using air conditioning can help minimize exposure to outdoor allergens.

5. Monitoring Symptoms: Keep a diary of your symptoms, noting when they occur and any potential triggers. This can help you and your healthcare provider identify patterns and make informed decisions about your management plan.


Conclusion
In summary, your symptoms suggest a combination of food allergies, environmental allergies, and possibly pet allergies. While it may be challenging to navigate these issues, implementing avoidance strategies, considering medication, and seeking professional guidance can help you manage your allergies effectively. If your symptoms continue to escalate or significantly impact your quality of life, it is essential to consult with an allergist or healthcare provider for further evaluation and treatment options. Remember, you are not alone in this, and there are effective strategies to help you cope with your allergies.
