What causes a pimple on the testicles?

Pimples on the testicles may be related to factors such as folliculitis, sebaceous cyst, epididymitis, testicular hydrocele, and testicular tumors. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid self-treatment.

1. Folliculitis

Bacterial infection of the hair follicles on the testicular skin may cause local redness, swelling, and bumps, often accompanied by pain or itching. It is necessary to keep the perineum clean and dry every day and avoid scratching. If secondary infection occurs, topical antibiotics such as mupirocin ointment and fusidic acid cream can be used as directed by the doctor. In severe cases, oral cefuroxime axetil tablets are required.

2. Sebaceous cyst

Blockage of the sebaceous gland duct forms a cystic mass that is hard and pushable. Usually no special treatment is required, but redness, swelling, heat and pain may occur when secondary infection occurs. You can use Ichthyostatin ointment as directed by your doctor to promote resolution, and perform cyst resection if necessary. Avoid squeezing and irritating the cyst area.

3. Epididymitis

Retrograde bacterial infection of the epididymis can cause nodular swelling, often accompanied by scrotal pain and fever. You need to rest in bed with your scrotum elevated, and use antibiotics such as levofloxacin tablets and cefixime dispersible tablets as directed by your doctor. In the chronic stage, hot compress can be used to relieve symptoms.

4. Testicular hydrocele

Failure of the sheath to close results in fluid accumulation that manifests as a painless cystic mass. A small amount of effusion can be observed, but when the fluid is large or affects daily life, a sheath inversion operation is required. Avoid strenuous exercise on a daily basis to aggravate scrotal sagging.

5. Testicular tumors

Painless induration occurs in the testicular parenchyma, which may be accompanied by a feeling of heaviness or dull pain. The diagnosis needs to be confirmed by ultrasound and tumor marker examination, and radical orchiectomy combined with radiotherapy and chemotherapy is selected according to the pathological type. Early detection has a better prognosis.

You should wear loose cotton underwear every day to reduce friction, and check the changes in testicular morphology by yourself every month. Avoid long-term riding or prolonged sitting that puts pressure on the perineum. If the pimple enlarges, ruptures, or becomes more painful, you should seek immediate medical attention from a urology department. It is forbidden to perform puncture or medication without authorization before diagnosis, so as not to interfere with the diagnosis or cause the spread of infection.
