Whether your condition is epididymitis or not, you still need to visit the doctor if you're having testicle pain, swelling, redness, or tenderness, or you're having trouble urinating.  Schedule an appointment to see your doctor as soon as you start experiencing symptoms. Be ready to talk about your recent history, including your recent sexual history. Be honest, as that's the only way the doctor can treat you properly. They've heard it all before. The doctor will want to check out your groin area and feel the affected testicles. While this may be a little embarrassing for you, it's necessary for diagnosis. If you're feeling a little anxious, know you're not alone, as many people feel uncomfortable in this situation.  Your doctor will check for tenderness in your lower back to look for possible kidney or bladder infections that may be contributing to your epididymitis. Your doctor may also collect a urine sample to check for a UTI. The doctor may also want to do a rectal exam to check your prostate. Because this infection can result from an STI, your doctor will want to run these tests. Typically, you'll provide a urine sample, and your doctor may swab the inside of your penis. While the test may be uncomfortable, it's usually not painful. Your doctor will also likely take blood tests including a C-reactive protein or an erythrocyte sedimentation rate test, as these can use the tests to detect any abnormalities that may be causing the infection. They may also be able to identify strains of bacteria in your blood. An ultrasound can help the doctor determine if your issue is epididymitis or testicular torsion. In younger men, this distinction can be difficult to make, and an ultrasound can help. They'll just pass a wand over the area to take a Doppler ultrasound. If blood flow to the area is low, it indicates testicular torsion. If it's high, it indicates epididymitis.
