What are the red dots on my glans without pain or itching?

Red dots on the glans penis may indicate dermatitis, with posthitis being the most common condition affecting the glans and foreskin. Patients with dermatitis often have phimosis or an overly long foreskin, leading to the accumulation of smegma due to a lack of attention to local hygiene. This accumulation, combined with bacterial infection, can cause localized symptoms such as flushing, red spots on the glans, burning sensations, and itchiness, although some patients may not experience itchiness in the early stages. The red dots on the foreskin and glans may gradually expand into a ring-like pattern.

A single red dot on the glans penis without itchiness is often indicative of posthitis. This may be due to an overly long foreskin and a lack of attention to hygiene, leading to inflammation of the foreskin and glans. In such cases, there is no need for concern. It is recommended to open the foreskin for daily cleaning and maintain dryness, which will lead to quick recovery. If the red dots continue to worsen, active treatment is necessary, especially for patients with an overly long foreskin. After uncleaned or sexual intercourse, there may be bacterial or fungal infections on the foreskin, which can cause posthitis, sometimes accompanied by a white,豆腐渣-like discharge. Proper daily cleansing can effectively prevent this. Red dots on the glans penis without itchiness may also be caused by trichomonas balanitis, annular ulcerative posthitis, acute superficial balanitis, or candidal balanitis. These conditions are harmful to the patient's health and require timely treatment with medication for clinical cure and recovery.
