I've had this small pain that comes and goes in my left testicle for as long as i can remember. I found out that there's a small weird lump on top of it.
Here's a picture: this isn't my penis btw it's a picture i found online but the lump looks pretty much identical.
The pain isn't sharp it's just dull and it doesn't bother me much. It isn't too distracting. It's noticeable but it doesn't stop me from exercising or anything.
I've had this for around a year i think. maybe more
