Where to massage for bronchial dilation?
There is no definite efficacy for the treatment of bronchiectasis with massage therapy. Generally, the main measure for bronchiectasis is to prevent respiratory infections. Bronchiectasis often presents symptoms of coughing up purulent sputum and may be accompanied by chest tightness, difficulty breathing, and hemoptysis. In patients with bronchiectasis, respiratory infections may exacerbate these symptoms. Therefore, preventing respiratory infections is crucial for bronchiectasis. Additionally, if the patient has obvious coughing and expectoration, mucolytic medications can be used to facilitate expectoration. If the patient experiences chest tightness and difficulty breathing, inhaling bronchodilators can help improve these conditions. For patients with bronchiectasis, if the lesions are localized and recurrent infections or hemoptysis occur, surgical treatment may also be considered.
Can I eat peaches with tracheitis?
Patients with bronchitis can eat peaches. Bronchitis usually refers to chronic bronchitis, and it is generally good for patients with chronic bronchitis to eat some fruits, such as peaches, pears, and apples. Additionally, it is important for patients with chronic bronchitis to follow a light diet and avoid spicy, stimulating, and overly greasy foods. Patients with chronic bronchitis should also consider quitting smoking, including avoiding secondhand smoke, as the disease is often related to long-term smoking. Quitting smoking can help slow the progression of the disease. Patients with chronic bronchitis also need to prevent respiratory infections, as respiratory infections can lead to acute attacks of chronic bronchitis. Repeated acute attacks can potentially accelerate the progression of chronic bronchitis.
How to distinguish a viral cold from a cold caused by exposure to cold weather
A cold caused by getting chilled can often present the same symptoms as a viral cold. This type of cold refers to a situation where, after exposure to cold, an individual's immune system becomes weakened, allowing pathogens residing in the respiratory tract to proliferate rapidly and thus cause a cold. In many cases, a cold from getting chilled is also viral in nature. Symptoms commonly seen in individuals with colds may include runny nose, sneezing, nasal congestion, sore throat, coughing, headache, muscle aches, fatigue, and sometimes a mild fever. However, sometimes a cold due to chilling may also lead to infection by other pathogens, such as bacteria, which can present clinically differently from a viral cold. In such cases, patients might not exhibit typical symptoms like clear nasal discharge or sneezing; instead, they might only show nonspecific upper respiratory symptoms. It is also possible for them to experience high fever, obvious sore throat, and swelling of the tonsils, which are signs of acute purulent tonsillitis, a specific type of bacterial cold.
What kind of cold is one that involves constant sneezing?
If sneezing persists and it's due to a cold, it could be a viral infection. It's important to note that sneezing caused by viral colds is usually self-limiting, meaning that the condition of the patient gradually improves on its own, and typically resolves completely within 7 to 10 days even without medication. If sneezing continues for more than a week without improvement, especially if it's long-term and recurrent, then allergic rhinitis should be considered. Allergic rhinitis may manifest as recurrent runny nose and sneezing. In such cases, it often requires appropriate management, including avoiding allergens, avoiding inhaling cold air, and possibly taking leukotriene receptor antagonists or antihistamines for treatment. (Please use medications under the guidance of a physician.)
Is the appetite good in the early stages of lung cancer?
In the early stages of lung cancer, generally, there is no obvious impact on the appetite. Most early-stage lung cancers do not show clinical symptoms. However, some patients may experience coughs or blood-streaked sputum if the tumor grows along the inner wall of the airway, stimulating the respiratory tract. Nevertheless, early-stage lung cancer typically does not metastasize or spread to the digestive tract. Thus, early-stage lung cancer usually does not affect the patient's appetite, and the patient's appetite generally remains unaffected. However, it is crucial to diagnose early-stage lung cancer because surgical removal at this stage can often achieve good results. Once it progresses to mid or late stages, the outcomes are usually poor, and the survival period is typically short. Therefore, it is advocated that people at high risk for lung cancer undergo regular chest CT screenings to check for early-stage lung cancer.
Symptoms of the common cold
The common cold usually manifests with symptoms such as runny nose, sneezing, sore throat, and coughing, often leading to a dry cough without significant phlegm. Additionally, the common cold may also accompany muscle aches, fatigue, and even headaches as general symptoms. Sometimes, patients with the common cold may also exhibit fever, though high fever is relatively rare. Regarding the common cold, the condition generally has a self-limiting nature, and symptomatic treatment usually leads to recovery. However, caution is still needed. Sometimes, the common cold can also coincide with pneumonia, although this is relatively rare. Close observation of the condition is necessary; if cold symptoms persist or are accompanied by high fever and purulent sputum, active investigation should be undertaken.
Can a pulmonary embolism cold cause a fever?
Pulmonary embolism combined with a cold can indeed cause a fever, which is a relatively common occurrence. However, it typically results in a low-grade fever. Additionally, it is important to note that if pulmonary embolism is combined with pulmonary infarction, it can also lead to a fever, usually manifesting as a low-grade fever. Therefore, pulmonary embolism itself can potentially cause a fever. Furthermore, it is crucial to be aware that if pulmonary embolism leads to a fever, it should not be misdiagnosed as a common cold or pneumonia. Especially in patients with concurrent pulmonary infarction, the presence of a fever, and subpleural patchy shadows seen on chest CT can resemble the manifestations of pneumonia. Care must be taken to avoid misdiagnosis as pneumonia, which could delay treatment for the patient and potentially lead to severe consequences.
Can early-stage lung cancer cause shoulder pain?
In the early stages of lung cancer, it generally does not cause shoulder pain. Early-stage lung cancer often does not involve critical structures and typically does not produce noticeable clinical symptoms. However, a small number of central lung cancers may cause symptoms related to coughing. Moreover, shoulder pain can occur in cases of lung cancer, often seen in superior sulcus tumors. A superior sulcus tumor, also known as a Pancoast tumor, is a tumor located at the top of the lung. As the tumor grows, it may compress the brachial plexus nerves, leading to symptoms such as shoulder pain and throat pain. It can also cause symptoms like enophthalmos (sunken eyeball) and pupil constriction. Therefore, when encountering these signs clinically, it is necessary to consider the possibility of a superior sulcus tumor and conduct examinations like a chest CT scan for evaluation.
Can I eat shrimp with a cold?
It is appropriate for cold sufferers to eat shrimp in moderation. For those with a cold, it is important to maintain a light diet and eat some fruits, avoiding spicy and greasy foods. However, they can consume protein-rich foods such as lean meat, fish, shrimp, and eggs. Additionally, cold sufferers should avoid alcohol, coffee, and strong tea. These dietary adjustments may help the patient's condition to recover on its own. However, it is important to note that although colds often have self-limiting characteristics, when symptoms are severe, it may be necessary to use cold medicines to alleviate symptoms. It is also important to be aware that a minority of patients may experience complications, so if cold symptoms persist, it is necessary to visit a hospital to avoid delaying treatment.
Can you run with acute bronchitis?
It is not recommended to run when suffering from acute bronchitis. For this condition, it is usually necessary to rest. During the acute phase of the illness, running and similar physical exercises are not advised as they can be detrimental to the patient's condition. Patients with acute bronchitis should also pay attention to maintaining a light diet, avoiding spicy and irritating foods. Appropriate symptomatic treatment should be given, such as using cough suppressant medications. If a patient has persistent cough symptoms or develops purulent sputum, it’s crucial to check for the possible presence of pneumonia. This may require a chest CT and a complete blood count. If the patient has bacterial pneumonia, antibiotic treatment is necessary. Moreover, it is important to note that although patients with acute bronchitis should not run during the acute phase, running and exercising regularly, enhancing nutrition, and avoiding staying up late are measures that can help prevent acute bronchitis.
