Prostate infection, other bacteria non-STD related.
What do you mean by wide range of problems if you don't mind me asking? And it only happens some mornings but definitely is discharge. But like I said all std test come back negative.
Non-specific urethritis could be a potential cause, or a urinary tract infection.
As Vance2335 suggested, ask for a swab test so it can be analyzed for a wide range of potential problems (especially if your STD tests came back negative).
All my std test come back negative. I had a urinary culture that also came back negative. But I still experience a yellowish discharge from my penis almost every morning and a slight burning sensation from time to time. I had gotten treated with Zithromax 3 different times since it has been happening as well as Metronidozole. What can be causing my symptoms if not chlamydia or gonorrhea?
The discharge should be swabbed and tested for what bacteria it is so the correct medication can be given.
