Did your urologist do an ultrasound and look at your prostate? Do a finger exam and feel it?
I think that needs to happen if it hasn't already, or maybe a cystoscopy. I think you're clearly negative for chlamydia, but that doesn't mean you don't have something happening in your prostate.
Ive had the same symptoms(ish) and diagnosed with CPPS a couple of years ago. Massive flare up in September so ill list below to try to help you out with what I figured out...
Discomfort on tip of penis and base,
Discomfort on urination but usually in morning or dehydrated,
Left testicle pain (diagnosed with Epididimitis)
Also had blood in urine and treated for UTI early on.
Meds ive taken since September (start)..
14 days Doxycycline x2 a day
5 days metronidazole x1 a day
10 days levofloxcin after the metronidazole ran out
Azithromycin 2 tablets day one then 1 tablet a day for 3 days(500mg and 250mg).
Co-amoxiclav 3 days a day after azithromycin
a week or 2 later
Azithromycin 2 tablets day one then 1 tablet a day (500mg every day for 3 days).
All STI tests came back negative INCLUDING Mycoplasma. I questioned about Ureaplasma but the doctor said one of the tablets would have sorted out that. Im doubtfull looking at guidelines but cant go any further than that.
What have I found out?
I have figured out that if I have hard stool or constipated I get a semany discharge in the toilet bowl. After research this suggests it could be normal prostatic fluid where the stool is pushing on the prostate. I took a laxative and sorted that bit out. Since then the clear discharge through at the day seemed to have eased up. I occasionally still get discomfort in the tip of the penis but this seems to be more than I think about it which could to me, indicate it is stress and anxiety related.
The pain in my testicle is constant and am yet to figure it out. I have some strong anti-inflammatory (starts with M..). I have stretching more incase it is related to CPPS and find there is moderate success but I will keep trying!
