Hello and welcome to HCM,
Pain and chills are suggestive of bacterial infection.
Although the tests for STIs have come out to be negative, I suggest you to get an urine examination as well as a
semen analysis done.
The pain in testis could be due to infection in the reproductive tract which starts from
epididymis, includes vas defers, seminiferous glands,
prostate and
penile urethra.
In case there is evidence of infection in the reproductive tract on semen analysis, appropriate antibiotics need to be taken.
Infections of reproductive tract can involve the
urinary tract also thus requirement of urine analysis.
In addition, if thrush is present in your partner, it needs to be treated.
Avoid unprotected sex till the thrush in your partner, your pain and chills are treated.
Thanks and take care
Dr Shailja Puri
