There is a small hard lump on the testicles

A small hard pimple on the testicle may be caused by a sebaceous cyst, or it may be caused by folliculitis. In addition, the possibility of epididymitis or orchitis cannot be ruled out. The cause needs to be determined in time and then treated symptomatically.

If the hair follicle openings in the testicles are blocked, causing sebum to be unable to be discharged from the body in time, resulting in sebum accumulation, a sebaceous cyst may form, which will appear as a small hard bump on the testicles. If the cyst is small, special treatment is generally not required, but if the cyst is large, surgical removal of the cyst can be used.；

If you often wear tight underwear or sit for long periods of time, causing your testicles to be in a humid environment, you are susceptible to Malassezia infection, which can lead to folliculitis. You may also develop small hard pimples on your testicles. You can cooperate with your doctor to apply topical erythromycin ointment for treatment, which can eliminate inflammation and infection, thereby promoting the resolution of small pimples.；

If you suffer from epididymitis or orchitis, the inflammation may irritate the epididymal tissue, resulting in swelling and congestion of the testicles, which may also appear as a small hard bump. You need to cooperate with your doctor to take antibiotics for treatment in a timely manner, such as levofloxacin, cefuroxime, etc.
