I am 18 years old and I have had epididymitis for 6 months now. At first it was very painful so I went to see a urologist who gave me antibiotics and anti-flammatories. Ever since, I have not been in any pain, but the swollen-ness comes and goes. Often times, my epididymis still gets very swollen as I can see and feel a large lump about 1/3 the size of my testicle. It also tends to get very swollen when I exercise, although I have been reframing from any physical activity to try to recover from this. How long will this take to go away??
