Some hidden pain in the testicles after urination may be related to testicular trauma, orchitis and prostate stones and other factors. 1. Testicular trauma: If the testicles are traumatized due to improper sexual position, hard object knocking and excessive pulling, etc., and in the process of recovery, the testicles are accidentally pulled when urinating, which can cause hidden pain in the testicles. 2. Testiculitis: Testiculitis refers to the inflammatory reaction at the testicles, and under the long-term stimulation of inflammatory factors, the testicles can produce pain. Accidentally touching the testicles when urinating may cause hidden testicular pain. 3. Prostate stones: When urinating, stones flushed into the prostate can cause radiating pain in the prostate, which can radiate to the testicles. The above symptoms may also be caused by other factors. Patients are advised to go to regular hospitals in time to find out the cause of the disease and choose the suitable method of treatment under the guidance of professional doctors, in order to strive for a speedy recovery.
