My scrotum was really swollen and bruised too, but it went away fairly quickly, within a couple of weeks if I remember right. From my understanding, some surgeons always act surprised when it happens, but my team told me it happens every time, and sometimes to a degree that looks alarming. It’s all harmless though, and eventually goes away.
The soreness in the scrotum is something that disappears very slowly in some cases. It’s not at all unusual to still have some weird aching feelings even nine to twelve months later. I’m five months past my surgery today, and there’s still some lingering pain. It does go away though, it just takes time for the nerves to heal. I should point out that the really bad pain from the surgery is gone rather quickly, and the lingering pain that I’m talking about is minor, but definitely annoying.
