The symptoms that you have mentioned are suggestive of torsion of testis. Torsion of testis is the twisting of
the spermatic cord, which cuts off the blood supply to the testicle and surrounding structures within the
scrotum. This condition is more common in puberty. Some men may be predisposed to testicular torsion because
of inadequate connective tissue within the scrotum. The other symptoms include swelling in one side of the
scrotum, nausea and vomiting, Light-headedness etc. Some other causes for testicular pain are epididymitis,
inguinal hernia, kidney stones etc. So, it is difficult to diagnose without proper examination. Please consult
surgeon for complete evaluation and treatment.
