Testicular pain and back pain could be caused by various things. Sometimes, testicular pain can be due to issues like infections, injury, or even a condition called epididymitis. Back pain, on the other hand, can stem from muscle strain, poor posture, or even problems with the spine. It's essential to get this checked out by a healthcare provider to pinpoint the exact cause. In fact, I recommend scheduling an appointment with your urologist. They can do a physical exam, possibly some tests, and figure out the best course of action to help you feel better.
