Hi. Thanks for your query. Noted your history of masturbation for 2 to 3 years and then do workout in gym for 5 months. Now there is some pain in left testis. Also whenever sperms comes out of penis, you feel pain in some vein above testis and also in left testis. Consulted various doctors, but no medicine works well. Also feel some problems in veins going down to legs....and feels pain in a vein backward going upward, feel very shy, embarrassed. Wants to know what is the problem, and wants the exact cure. The pain on masturbation in the testis can be due to blockage of the vas deference or the epididymis. Prostatitis Muscular pull by the cremaster and causing the occasional testicular pull and partial testicular torsion and so on. I would advise the you to have a proper ultrasonography of the abdomen and the scrotum with color mode also. Tests of the blood, urine and semen. Per-rectal examination for prostate and a clinical evaluation to finalize the diagnosis. Only a proper medicine can help to give guideline as to whether you need medicines and/or some corrective surgery.
