1. A lump or swelling near your testicles, may not cause harm but it is still important you see your doctor so that he or she can determine what might have caused the bump, since they can be normal like you may be feeling the epididymis
, the tightly coiled tube where sperm are stored.
2. Diagnosing the cause can be done based on the signs and symptoms it's causing and the location and feel of the mass thus additional visualization is usually done with ultrasound imaging, urine or blood tests may be done to test for a bacterial or viral infection.
3. Even if you're not experiencing any other symptoms,you should be examined by a doctor for accurate diagnosis and treatment. [to rule out varicocele
, hernia, testicular cancer
at an early stage, and will rule out past history of mumps, glandular fever
or simple flu/cold]
. Treatment will depend on the underlying cause of the bump. [if any]
