Hi. Thanks for your query. Noted your history of big lump under your right ball, been researching and think it s the epididymis. It s been hurting for a week now, taking antibiotics (guessing that it s a bacterial infection) and it seems to be helping with the pain and began wearing supporters too. But the lump is still there, which really concerns you. The best way to get a proper diagnosis is investigations of the blood, urine, stool, semen and ultrasonography with color doppler examination and clinical evaluation by a General Surgeon or an Urologist to get a proper medical or surgical treatment. Complete the courses till you get a cure otherwise this becomes chronic. I hope this answer helps you to get an early and proper diagnosis and proper treatment.
