Introduction
In general, bloody nasal discharge may be caused by dry air, improper diet, trauma, upper respiratory tract infections, allergic rhinitis, or other reasons. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. In daily life, it is recommended to maintain a positive mindset, avoid spicy, irritating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.

In general, bloody nasal discharge may be caused by dry air, improper diet, trauma, upper respiratory tract infections, allergic rhinitis, or other reasons. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Specific analysis is as follows:

1. Dry air: Dry climates or indoor environments can cause the nasal mucosa to become dry, making it more susceptible to damage and bleeding. In such cases, nasal mucus may contain blood streaks or clots. Attention should be paid to physical changes when environmental temperatures fluctuate suddenly; wearing a mask can provide protection.

2. Improper diet: Long-term consumption of excessive spicy, hot, or pungent foods may lead to congestion of the nasal mucosa, increasing the risk of bleeding. It is recommended in daily life to avoid prolonged intake of spicy foods and to increase fluid intake appropriately to relieve discomfort.

3. Trauma: External impact or injury to the nose may damage the nasal mucosa or blood vessels, resulting in bleeding. Nasal congestion and pain may accompany such injuries. If bleeding is mild, it can be managed by applying pressure with sanitary tissue and promptly rinsing the nasal cavity with clean water.

4. Upper respiratory tract infection: Caused by viral or bacterial infection of the upper respiratory tract, this condition leads to abnormalities due to pathogenic stimulation. Dress appropriately according to weather changes, maintain warmth, and follow medical advice to use medications such as acetaminophen tablets, ibuprofen tablets, or compound licorice tablets for treatment.

5. Allergic rhinitis: An inflammatory response of the nasal mucosa triggered by allergens, leading to congestion and swelling of the nasal mucosa. Congested blood vessels are more prone to injury, which may result in bloody nasal discharge. It is important to keep living areas clean and follow medical guidance in using medications such as loratadine tablets, cetirizine hydrochloride tablets, or ebastine tablets to alleviate symptoms.

In daily life, it is recommended to maintain a positive mindset, reduce intake of spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.

Can ear blockage after a cold resolve on its own?
In general, whether ear blockage following a cold can resolve on its own depends on the severity of the condition and the individual's recovery ability. If discomfort occurs, prompt medical attention is recommended. During a cold, it's important to actively treat the underlying illness and relieve nasal congestion. The nasal passages can be gently cleared to maintain patency. Avoid forceful nose-blowing, which may push nasal secretions into the Eustachian tube.

Is a low body temperature in the morning a sign of a cold?
If low body temperature in the morning is accompanied by typical cold symptoms such as nasal congestion, runny nose, sore throat, and mild cough, it may indicate the onset of a cold. In the early stage of a cold, the body's immune system activates, causing some individuals to experience temporary fluctuations in body temperature and mild chills, which may manifest as lower morning temperatures. This may later progress to fever or worsening symptoms; therefore, assessment should be based on the overall clinical presentation.

Can people with a cold take Cordyceps militaris?
If after a cold you only have mild nasal congestion and runny nose, without serious discomfort such as fever or sore throat, and if you have previously consumed cordyceps militaris (Jinchanhua) without allergic reactions or gastrointestinal discomfort, consuming a small amount is generally safe. The nutrients in cordyceps militaris may help support physical strength. At this time, when your body's burden is light, moderate consumption usually does not worsen cold symptoms or cause adverse reactions.

Can procaterol be taken together with dextromethorphan?
If coughing is accompanied by noticeable wheezing and airway spasms, with little or no sputum, and a doctor diagnoses conditions such as bronchial asthma or asthmatic bronchitis, these two medications may be taken together under medical guidance. Procaterol relaxes the bronchi and relieves wheezing, while dextromethorphan suppresses the cough center and reduces dry cough symptoms. Together, they provide more comprehensive relief from respiratory discomfort and help restore smooth breathing.

Can I wear OK lenses if I have a cold and runny nose?
If you have only mild nasal discharge after a cold, without symptoms such as fever, frequent sneezing, or red and swollen eyes, and can strictly follow the OK lens care routine—thoroughly washing hands before handling lenses, cleaning the lenses with dedicated solution, and avoiding eye rubbing—short-term wear is generally not associated with serious problems. In such cases, the eyes are minimally affected, and proper lens care can reduce the risk of infection and maintain the effectiveness of the lenses.

Is a person still contagious after fever subsides due to a cold?
If a cold is caused by the influenza virus, or if symptoms such as persistent cough, sore throat, and runny nose remain after fever subsides—even if the fever has only been gone for less than 24 hours—there may still be infectivity. Influenza viruses are highly contagious and can persist for a long duration; even after the fever resolves, residual virus may remain in the body and spread via respiratory droplets. The persistence of symptoms also indicates that the virus has not been completely eliminated, meaning there remains a risk of transmission.
