Hi. Thanks for your query. You have got a typical presentation of repeated testicular torsion. This is evidenced by repeated pains in the left testicle , which fades away after adjusting the testicle, the pain is very severe as if somebody kicked on the nuts in your language; occasionally comes during or after an orgasm - this happens as the cremaster muscle is also contracted during this period causing the testis to be pulled up and at the same time twisted. I would advise you in such a situation the following: -Ultrasonography and color doppler examination of the scrotum. -Manual examination by a General Surgeon or Urologist to affirm -Routine tests of blood, urine for fitness. -Small definitive surgery of anchoring the testis will solve your problem for lifetime.
