So for a while I have had this large lump roughly the same size as my testicals attached to my left festival. The first time I examined it was a several months ago but I do so usually about every month and as far as I can tell based on the fact that when I shine a light on the lump the whole thing illuminates and is distinctly separate from my testicle I think it may be a spermatocele. Also a little while ago I had a general check up where the doctor examined the area but I'm not sure if she didn't notice it or just dismissed it but she said everything was healthy etc... But now there is a small ball attached to the outside just around the area the large lump connects, as far as I can tell it too illuminates with light. I'm planning to see a doctor at some point but until then any advice would help. By the way I am also 16 years old so I think normally it would be to early for tc?
