STDs :: Gonorrhea After Fellatio (oral) Symptoms?

I received fellatio 11 days ago, and after about 2 days, intermittently, I would feel a slight sting at the end of my penis, and then  in the last few days, it has become a bit worse when I urinate.. Not unbearable, mind you, but very noticeable..

I also noticed tonight a little bit of white discharge.

I have researched symptoms to death, and I cannot seem to find any answers to questions like:

If you have burning when urinating (as some people are asymptomatic) does it burn

a) every time you urinate?

b) if you aren't drinking enough water, and maybe it is more acidic? (Sometimes it doesn't sting at all, I mean, until this morning, I was 24 hours without symptoms

c) for the duration of the pee? (for me it just happens at the end, and for a little bit after)

If there is discharge, is it constant, or could it perhaps just happen a few times a day?

Every site also says that it should be treated ASAP to avoid complications.. exactly how long does this mean? It causes problems after 2 weeks? 2 months? None give a time frame.

A doctor prescribed me 250mg Ciprofloxacin 3x a day.. I am on day 3, but it seems to be getting worse..

- Even though the clap is indicated for this, many sites also say that due to resistant strains, this stuff is pretty useless..

And the big question - is it possible to have a strain, which is simply not treatable, for the rest of my life? (or is just just a matter of bombarding my body with more and stronger medications until it goes away?
