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.
Is asthma considered respiratory failure?
Asthma and respiratory failure are two distinct concepts. Asthma is a disease, whereas respiratory failure is a clinical outcome resulting from a series of diseases. During an acute asthma attack, there is also a possibility of respiratory failure occurring, and in severe cases, it can lead to serious respiratory failure requiring interventions like tracheal intubation and mechanical ventilation. Therefore, acute asthma attacks require active intervention. Treatments often include nebulized inhalation of short-acting bronchodilators and even intravenous administration of corticosteroids to handle the acute episode. Short-term intravenous use of corticosteroids can also help in controlling the acute attack.
What to do if you are afraid of cold with type A influenza?
Patients with Type A influenza who are sensitive to cold often need to pay attention to appropriate warmth. Additionally, monitoring the patient's temperature is necessary, and if the patient has a fever, it is often necessary to use antipyretic medications to control their temperature and alleviate symptoms of chilliness and cold sensitivity. For Type A influenza, it is generally recommended to start antiviral treatment with a neuraminidase inhibitor orally within 48 hours of onset. Antiviral treatment can help shorten the duration of illness and reduce the complications related to Type A influenza. Moreover, in cases of Type A influenza where the patient is sensitive to cold, it is also important to pay attention to a light diet and proper hydration. Avoiding staying up late and excessive physical exertion are non-pharmacological measures that also help with the condition.
Can you drink tea when you have a cold?
It is not recommended to drink tea when having a cold; it is advised that patients drink more plain water instead. Patients also need to maintain a light diet and eat some fruits, and it’s recommended to avoid both tea and carbonated beverages, as well as alcohol. For conditions like the common cold, it is important to avoid staying up late and overexerting oneself. The common cold is usually self-limiting, meaning it will typically resolve on its own as the patient's immune system fights off the illness. However, if the symptoms of a cold are severe, it may be necessary to take medication for symptomatic treatment. It is also important to note that while the common cold is usually self-limiting and does not often lead to serious consequences, complications can sometimes arise. For example, it could lead to acute sinusitis or bacterial pneumonia. If a cold sufferer's symptoms persist or worsen, it is important to seek medical attention promptly for proper treatment.
Can I eat lamb if I have pulmonary embolism?
Patients with pulmonary embolism can appropriately eat mutton, as it is acceptable in their case. For pulmonary embolism, it is advocated to follow a light diet, avoiding spicy, irritating food, and excessively greasy food to prevent aggravating the gastrointestinal burden of the patient. Additionally, it is acceptable for patients with pulmonary embolism to consume some meat, as long as it is not fatty meat. Once diagnosed with pulmonary embolism, patients should receive active treatment, which often requires anticoagulant therapy. If the condition is not too severe, simple anticoagulant treatment may allow the patient’s condition to recover. However, if the pulmonary embolism is more severe, thrombolytic therapy may be necessary. After thrombolytic treatment, vascular anticoagulant therapy is given to manage the patient's condition.
What should I do about dry cough and wheezing caused by lung cancer?
Patients with lung cancer presenting with dry cough and wheezing often require treatment to suppress coughing, alleviate wheezing, and address the symptoms. It is also important to check if the patient has concurrent obstructive pneumonia. Lung cancer combined with obstructive pneumonia can also lead to dry cough and wheezing. In such cases, anti-infection treatment is needed, along with treatment specifically targeting lung cancer itself. Dry cough and wheezing in lung cancer often suggest that the cancer may be in the middle to late stages, where the chances of surgery are generally small. However, it is still necessary to complete relevant examinations to further assess the condition. If the patient is eligible for surgery, surgical treatment should be considered. If the patient is indeed in the middle to late stages of lung cancer and is not suitable for surgery, chemotherapeutic drugs are needed for treatment. Sometimes, targeted drugs can be chosen for treating advanced-stage non-small cell lung cancer. In cases of advanced non-small cell lung cancer with driver gene mutations, targeted therapy might even be the preferred treatment option.
