Introduction
In general, the presence of a pus-filled lump at the entrance of the ear accompanied by foul-smelling discharge may be related to foreign bodies in the ear canal, preauricular sinus, sebaceous cysts, folliculitis, or furuncles. Treatment options include medication or surgical intervention. If symptoms are severe, it is advisable to seek medical attention promptly to avoid delaying diagnosis and treatment. It is also important to maintain good daily habits.

Under normal circumstances, the presence of a pus-filled lump at the ear opening accompanied by foul-smelling discharge may be related to foreign bodies in the external auditory canal, preauricular sinus, sebaceous cysts, folliculitis, or furuncles. Treatment options include medication or surgical intervention. Specific causes are analyzed as follows:

1. Foreign Body in the External Auditory Canal

During ear cleaning, foreign objects may enter the external auditory canal and cause bacterial infection, leading to pus secretion with an unpleasant odor. Under medical guidance, patients can use medications such as piperacillin sodium for injection and ibuprofen sustained-release capsules to relieve symptoms.

2. Preauricular Sinus

A preauricular sinus is a congenital hereditary condition. Squeezing the area may result in the discharge of white secretions accompanied by a noticeable odor. Maintain proper hygiene and avoid squeezing the area.

3. Sebaceous Cyst

Sebaceous cysts are typically caused by blockage of sebaceous gland secretions at the hair follicle opening. The cyst accumulates sebum and keratin, forming a pus-filled lump that discharges pus. Patients may undergo surgical excision under medical supervision.

4. Folliculitis

Folliculitis is usually caused by Staphylococcus aureus invading and infecting hair follicles, resulting in red papules. These papules may develop into pustules containing white or yellowish pus, which may rupture and discharge pus and blood. Under medical guidance, patients may take medications such as cefuroxime axetil tablets or doxycycline hydrochloride tablets for treatment.

5. Furuncle (Boil)

A furuncle is an acute suppurative inflammation of the hair follicle and sebaceous gland. It presents as a red nodule; as the condition progresses, a yellow-white pus head forms in the center of the hard nodule. After rupture, pus is discharged. Patients may require incision and drainage under medical guidance.

If symptoms are severe, prompt medical attention is recommended to prevent disease progression. Maintain healthy lifestyle habits and avoid spicy or irritating foods to promote recovery.

Does whooping cough still require medication if there is still an occasional cough at night?
If pertussis has entered the recovery phase, and the patient has completed a full course of standardized treatment, with daytime coughing nearly resolved and only occasional mild coughing at night—without other symptoms such as fever, shortness of breath, or vomiting—medication may generally be discontinued after medical evaluation. At this stage, the mild cough is usually a normal response during the healing process of the respiratory mucosa, and the body can gradually recover on its own without continued reliance on medication.

Does Lianhua Qingwen treat allergic asthma?
The core effects of Lianhua Qingwen are clearing away epidemic toxins, detoxification, promoting lung function, and relieving heat. It is primarily used to treat influenza due to heat-toxin attacking the lungs, and is not intended for the treatment of allergic asthma. Allergic asthma results from an abnormal immune response to allergens and requires targeted anti-inflammatory and anti-allergy treatments. Patients with allergic asthma should seek timely evaluation and standardized treatment at a respiratory medicine department.

Can mild pulmonary hypertension be cured?
In general, whether mild pulmonary hypertension can be cured depends on whether the underlying cause is clear and removable. Cases secondary to left heart disease or lung diseases often improve once the underlying cause is addressed; however, idiopathic pulmonary hypertension is difficult to cure completely and requires long-term management. Patients with mild pulmonary hypertension should avoid smoking and excessive alcohol consumption, refrain from strenuous exercise and high-altitude environments, and reduce stress on the lungs in daily life.

Can Lianhua Qingwen Granules treat yellow nasal discharge?
Lianhua Qingwen Granules are effective in relieving yellow nasal discharge caused by heat-toxin attacking the lungs, but less effective for cases due to cold-wind invasion or bacterial infection. If yellow nasal discharge is accompanied by symptoms such as fever, sore throat, cough, and yellow, thick phlegm—indicative of heat-toxin affecting the lungs—Lianhua Qingwen Granules can be beneficial. Containing ingredients like Forsythia suspensa (Lianqiao) and Lonicera japonica (Jinyinhua), this formula helps clear epidemic toxins, resolve heat, and promote lung function, thereby improving the aforementioned associated symptoms.

Does whooping cough still cause coughing at night during the recovery phase?
If in the early recovery phase of pertussis, where severe coughing symptoms have only recently subsided and the respiratory mucosa is still healing, occasional mild coughing—perhaps just one or two episodes at night—may occur. This type of cough is usually irregular, not accompanied by shortness of breath, vomiting, or other discomforts, and its frequency gradually decreases as recovery progresses. It represents a normal part of the body's healing process.
