Male <30, history of ngu w/ negative std result (x2 >30 days ago), yeast like sympt, yellowish discharge, very little pain, some internal itch, strings in urine, what gives? treated twice w/ rocephin (ceftriaxone).

Non-gonococcal : Non-gonococcal urethritis is usually due to higher forms of bacteria which do not have a cell wall, and as such are going to be resistant to treatment with agents that have their affects on cell wall synthesis (like ceftriaxone). This should be treated with other drugs. Cannot diagnose what you have, but see a urologist and get treated appropriately.

Maybe treated: For wrong std . Should be cultured and pan treated, not just rocephin, (ceftriaxone) which is obviously inadequate.
