Prostate cancer and testicular pain

The prostate, urinary tract, groin, and testicles share nearby nerves and connected structures, so discomfort can be felt in more than one area. Prostatitis, epididymitis, a urinary infection, hernia, injury, kidney stone, or testicular twisting can cause pain. Prostate cancer itself may cause pelvic discomfort, while treatment can change sensations or affect nearby tissues. Sudden severe pain, swelling, a high-riding testicle, nausea, or vomiting raises concern for a testicular emergency rather than pointing to one specific diagnosis.

Arrange medical review for new, persistent, recurrent, or one-sided pain. Describe whether it began suddenly, the exact side, swelling, urinary symptoms, fever, discharge, injury, and any recent procedure or cancer treatment. A clinician may examine the abdomen, groin, and scrotum, test urine, and arrange ultrasound or other tests. Treatment depends on the cause; it may involve antibiotics for infection, pain relief, management of urinary symptoms, or adjustment of cancer treatment. Prostate Cancer and Difficulty Passing Urine offer useful related reading.

Go to an emergency department immediately for sudden intense testicular pain, rapid swelling, nausea or vomiting with testicular pain, a testicle sitting higher than usual, severe pain after injury, fever with marked illness, or inability to pass urine. These problems can need prompt treatment. Contact your oncology team for pain that follows a procedure, continues despite prescribed medicine, or occurs with new pelvic or back symptoms.

Ask whether the pattern suggests infection, inflammation, referred pain, or a testicular emergency, and whether an ultrasound or urine test is needed. Check which pain medicines are compatible with your cancer treatment and what changes should prompt immediate reassessment.
