What causes pimples on the back accompanied by itching?
In general, acne on the back accompanied by itching may be caused by various factors such as puberty, sweat and friction, folliculitis, eczema, or allergic dermatitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:
1. Puberty
Hormonal changes during adolescence may lead to acne and itching on the back. Maintaining good personal hygiene and regularly cleansing the skin can help.
2. Sweat and Friction
Excessive sweating after exercise or in hot environments, combined with clothing friction, may trigger acne and itching on the back. Promptly changing into clean, breathable clothing and avoiding prolonged contact with tight garments can reduce irritation.
3. Folliculitis
Folliculitis is usually caused by bacterial infections such as Staphylococcus aureus. These microorganisms multiply within hair follicles, causing inflammation that leads to redness, swelling, acne formation, and itching. Symptoms may also include fever and swollen local lymph nodes. Treatment may include medications such as mupirocin ointment, erythromycin ointment, or doxycycline hydrochloride tablets, used under a doctor's supervision.
4. Eczema
Eczema is associated with genetic and environmental factors. Impaired skin barrier function allows external irritants to penetrate the skin more easily, triggering inflammatory responses that result in acne-like eruptions and itching. Dryness and flaking of the skin are commonly observed as well. Symptoms may be relieved with medications such as cetirizine hydrochloride tablets, prednisone acetate tablets, or compound glycyrrhizin tablets, taken as prescribed by a physician.
5. Contact Dermatitis
Contact dermatitis is typically triggered by abnormal immune responses, genetic predisposition, or exposure to allergens. When the skin on the back comes into contact with certain sensitizing substances, an allergic reaction may occur, resulting in acne-like lesions and itching. Additional symptoms may include a burning sensation or swelling of the skin. Treatment options include cetirizine hydrochloride tablets, loratadine tablets, or prednisone acetate tablets, used under medical guidance.
In daily life, it is important to develop healthy habits, maintain a light diet, and engage in moderate physical activity.
