Dull testicular pain, belly button lump....antibiotics haven't

This might be two different issues......or maybe they are connected.

Dull pain in one testicle, started after getting married and having a major increase in having sex.
Went to doctor, did an ultrasound....couldn't determine. Thought it might be an epitiditize (sp) and gave me antiobotics.
Dull pain didn't go away.
Saw a urologist, put me on a stronger antibiotic. Didn't work.
Saw a different urologist, he thought maybe I had a prostrate infection and the testicle pain was a side effect, so I took cypro for two months.
The five months of various antibiotics knocked off about 75% of the pain.
But it still is there. If I have sex more than 2-3 days in a row, it hurts more.
NOW........I guess I will go back to the urologist again????
The pain is a dull pain in the bottom of my left testicle. Comes and goes throughout the day.
Any ideas?

Second thing, and I don't know if this is related.
Around the same time, I noticed a small lump in my belly button.
Over the past six months it has gotten bigger, so now it takes up about 1/4 of my belly button space.
Doesn't hurt ....unless you push on it. And sometimes if I'm doing some heavy lifting it stretches a bit.
Since it doesnt really hurt I haven't had it checked out.
But I decided to look up belly button lumps and it - according to some websites - is probably a umbilical hernia maybe.

Now I'm wondering if I have some type of hernia and that is the reason that for the belly button lump and the testicle pain???
