I am 29 years of age unmarried, due to my prolonged sitting work condition i have a SCIATICA nerve pain on the left side leg, back and hip. Whenever I feel tha pain, the left side testicle also got pain. my question is, is this also one of the symptoms of SCIATICA or any other major problem? Please suggest me any solution to this testicle pain. But there is no pain when penis erection and ejaculation. There is no swelling on the testicle, both side of testicle feels same size and same temperature (cool). i am worried and confused. if this leads to infertility? Please help me to resolve my problem.
