Left testicle and inner left thigh pain.

I am 32 yrs old. I have pain in my left testicles and inner left thigh pain. I have this pain for almost an year. Its a mild pain and mostly I can tolerate it, but sometimes when I cant tolerate I am mentally disturbed and I cant concentrate much in my work. I am a software engineer and hence I always sit in the chair. When I sit in the chair continuously I have more pain. After doing some stretching exercises and after sleep the pain disappears. I also observed that have much of a pain since there my testicles was always contracted because of cold climatic conditions. But in summer time my testicles get loosened up and hence whenever I sit in the chair continuously or whenever I consulted an urologist, he tested me and said I am normal but still he advised me to perform a ultrasound scrotum test. The following is the report of the test "Both testis show uniform echotexture. Both epididymis show normal echotexture. The venous plexus in both scrotal sacs show no obvious evidence .
