Ive had a hard pebble sized lump on top of my right testicle near the epididymis since I was 11 years old. I never got it looked at and I'm 23 now. Since then I found another same sized lump on the same testicle but actually on the epididymis itself and my testicle is noticeably larger. For the past year I've been experiencing dull aches in my lower right abdomen everyday that sometimes moves to my lower back, hip, leg and flanks. The pain is very dull and seems to be more noticeable at night. I've also noticed a change in my bowels that include broken or loose stool and sometimes what I think might be small amounts of red blood in my stool. I've been so stressed about it for the past year so I finally set up an appointment but I'm so scared and anxious about what to expect. what can I expect?
