Painful bump in urethra (male)

I have a painful bump in my urethra. It burns when i urinate and it hurts when i get an erection. I’ve had this for a few weeks now. I’m thinking maybe it’s a uti? It hurts when i press down on any part of my penis shaft but especially if i press down on the bump. I can’t see the bump as it’s not on the surface of my penis. What do you think it could be?

the burning when urinating may be a uti also it can cause the urethra to become inflamed if u have been sexually active recently u may need full std check
