I have been coughing continuously, and recently my body has been feeling increasingly weak?

Hello doctor, I've been coughing since early December and it's now early February.
At first, I thought it was just a cold, so I didn't seek medical attention.
A few days before New Year's Eve, I started seeing a doctor and took some medication, but I felt nauseous and had the urge to vomit, so I stopped taking the medicine.
The day before New Year's Eve, I felt even worse and ended up vomiting a lot at night.
The doctor said I likely had a viral gastroenteritis, which caused these symptoms.
After taking new medication, my gastrointestinal issues improved, but I then developed a cough, nasal congestion, and soreness in my back and shoulders.
On the fifth day of the Lunar New Year, my mom got me some cold medicine, and I've also been drinking licorice herbal tea.
As of today, February 17, my cough persists, but I occasionally experience pain when breathing in my right chest.
My boyfriend was diagnosed with pneumonia in November, and by the end of January, he was found to have tuberculosis, which has made my family very worried and they want me to go to the hospital for tests, including a sputum test.
However, the doctor said I need to provide sputum first thing in the morning, but I can't seem to cough anything up until a couple of hours after waking up.
I find this testing method quite inconvenient.
I would like to ask if there are any other tests available that could help diagnose my condition?

Dear Sam: Coughing for three weeks and testing sputum is a basic concept in tuberculosis screening.
Since your boyfriend is also a pulmonary tuberculosis patient, you should definitely get tested.
The first sputum sample in the morning is generally more accurate, but it doesn't mean that it has to be the first sample; as long as you follow the correct sputum collection technique as instructed by a healthcare professional, it is acceptable.
Currently, no other tests can replace sputum examination.
Changhua Hospital cares about you.

More Info

Persistent cough and weakness can be quite concerning, especially when they persist for an extended period, as you have experienced since December. It is understandable that you are looking for alternatives to sputum tests, particularly given your current symptoms and the context of your boyfriend's recent diagnosis of tuberculosis (TB).
Firstly, it is important to recognize that a persistent cough can have various underlying causes, including infections (like viral or bacterial pneumonia), allergies, asthma, or even more serious conditions such as tuberculosis or lung cancer. Given your symptoms of cough, chest pain, and the recent history of your boyfriend's lung issues, it is prudent to seek further evaluation.

While sputum tests are a common method for diagnosing respiratory infections, including TB, they are not the only diagnostic tools available. Here are some alternatives that you might consider discussing with your healthcare provider:
1. Chest X-ray: This imaging test can help identify abnormalities in the lungs, such as infections, fluid accumulation, or masses. It is often the first step in evaluating persistent cough and can provide valuable information about your lung health.

2. CT Scan: If the chest X-ray shows any abnormalities or if your doctor has a high suspicion of a serious condition, a CT scan may be recommended. This imaging technique provides a more detailed view of the lungs and can help identify issues that a standard X-ray might miss.

3. Bronchoscopy: This procedure involves inserting a thin tube with a camera into the airways to directly visualize the lungs and air passages. It can also allow for the collection of samples from the lungs, which can be tested for infections, cancer, or other conditions.

4. Blood Tests: Certain blood tests can help identify infections or inflammatory conditions. For example, a complete blood count (CBC) can indicate the presence of an infection, while specific tests can check for markers of inflammation or autoimmune diseases.

5. Tuberculin Skin Test (TST) or Interferon Gamma Release Assays (IGRAs): If there is a concern for tuberculosis exposure, these tests can help determine if you have been infected with the TB bacteria, even if you do not have active disease.

6. Allergy Testing: If allergies are suspected to be contributing to your symptoms, allergy testing can help identify specific triggers.

7. Pulmonary Function Tests: These tests measure how well your lungs are working and can help diagnose conditions like asthma or chronic obstructive pulmonary disease (COPD).

Given your symptoms of chest pain and the context of your boyfriend's TB diagnosis, it is essential to communicate your concerns to your healthcare provider. They can guide you on the most appropriate tests based on your clinical history and current symptoms.

In the meantime, managing your symptoms is crucial. Staying hydrated, using a humidifier, and avoiding irritants (like smoke or strong odors) can help alleviate coughing. If you experience worsening symptoms, such as increased chest pain, difficulty breathing, or fever, seek medical attention promptly.

Lastly, while sputum tests may seem inconvenient, they are a valuable tool for diagnosing respiratory infections. If you are unable to produce sputum in the morning, discuss this with your doctor; they may have alternative methods for collecting samples or may suggest other diagnostic approaches.

In summary, persistent cough and associated symptoms warrant thorough evaluation. There are several diagnostic alternatives to sputum tests, and your healthcare provider can help determine the best course of action based on your specific situation. Prioritize your health and seek medical advice to address your concerns effectively.
