If the testicles hurt when gently pinched, it is not a normal situation and is abnormal. It is recommended to go to the hospital for relevant examinations to clarify the possible causes. Under normal circumstances, the testicles have a slightly hard texture of the envelope, a tough feeling to touch, and a special discomfort, but it will not be a significant painful feeling. If suffering from obvious painful sensation, the following conditions are mostly considered: 1. Testicular infection, often seen as a result of urinary tract infection or unclean sexual contact, leading to mycoplasma and chlamydia infection. This is when the epididymis is first infected, further causing testicular infection, which can appear to increase in size and painful when touched. It is necessary to go to the hospital for urinalysis and blood test, scrotal ultrasound, etc. to further exclude; 2. If the pain is accompanied by a significant increase in testicular volume and hardening of the testicle when gently pinched, testicular tumor is mostly considered to exist. It is recommended to go to hospital for testicular tumor indexology test, as well as testicular CT and ultrasound examination to further rule out.
