Persistent coughing can be a frustrating and concerning symptom, especially when it lingers for an extended period. Based on your description, it seems that you have been experiencing a dry cough that worsens during colds and is accompanied by a scratchy throat. You also mentioned that even after other cold symptoms resolve, the cough persists, which can be quite bothersome.

There are several potential causes for persistent coughing, and understanding these can help guide you toward effective management and treatment options. Here are some common causes:
1. Postnasal Drip: This is a frequent culprit for chronic coughs. When mucus drips down the back of the throat, it can trigger a cough reflex. This often occurs in conjunction with allergies or sinus issues, which can lead to throat irritation.

2. Allergies: Allergic rhinitis can cause symptoms like a scratchy throat and dry cough. Common allergens include pollen, dust mites, pet dander, and mold. If you have a history of allergies, this could be a significant factor.

3. Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat and lead to chronic coughing. If you notice that your cough worsens after eating or when lying down, GERD might be a consideration.

4. Asthma: This condition can present as a chronic cough, especially if it is dry and accompanied by wheezing or shortness of breath. Asthma can be triggered by various factors, including allergens, cold air, and respiratory infections.

5. Chronic Bronchitis: If you are a former smoker or have been exposed to irritants, chronic bronchitis could be a concern. This condition is characterized by a persistent cough that produces mucus.

6. Environmental Irritants: Exposure to smoke, pollution, or strong odors can lead to chronic coughing. If you have recently moved to a new area or changed your environment, this could be a factor.

Given that you have already consulted both traditional Chinese medicine and Western medicine without resolution, it may be beneficial to take a more comprehensive approach. Here are some steps you can consider:
- Consult an Allergist: If allergies are suspected, an allergist can perform tests to identify specific triggers and recommend appropriate treatments, such as antihistamines or nasal corticosteroids.

- Evaluate for GERD: If you suspect that acid reflux might be contributing to your symptoms, consider discussing this with your healthcare provider. Lifestyle modifications, dietary changes, and medications can help manage GERD.

- Asthma Assessment: If you have a family history of asthma or experience wheezing, it might be worth getting a pulmonary function test to rule out asthma as a cause of your cough.

- Lifestyle Modifications: Staying hydrated, using a humidifier, and avoiding known irritants can help alleviate cough symptoms. Additionally, practicing good throat hygiene, such as gargling with salt water, may provide temporary relief.

- Follow-Up Imaging: If your cough persists despite these interventions, consider discussing further imaging or tests with your healthcare provider to rule out any underlying conditions.

In conclusion, while persistent coughing can be a nuisance, it is essential to identify the underlying cause to determine the most effective treatment. If your symptoms continue or worsen, do not hesitate to seek further medical advice. Chronic coughing can lead to complications such as sleep disturbances, fatigue, and even rib fractures in severe cases, so addressing it promptly is crucial. Thank you for your inquiry, and I hope you find relief soon!
