Hello, A very warm welcome to AMD forum of doctors. Penile discharge can be abnormal discharge of fluid which
is neither semen nor urine. A transparent penile discharge upon straining is normal prostatic fluid. If the
discharge is opaque white or associated with itching or burning sensation then the probable cause could be STD
or non-specific urethritis. Most common cause of abnormal penile discharge can be gonococcal urethritis which
is transmitted by sexual intercourse. Another cause for discharge can be non-gonococcal urethritis caused by
Chlamydia, Mycoplasma, Ureaplasma and Trichomonas and rarely Herpes simplex. Third possibility can be
non-specific urethritis caused by irritant clothing, soap, or detergents etc. If the discharge is associated
with change in color, burning, frequent urge to pass urine, rash or swollen lymph nodes then STD causes should
be ruled out with the help of STD clinic or urologist. A urethral swab test or morning urine sample may help
you rule out any infection. Routine tests to detect all the STD infections are not available therefore
non-gonococcal urethritis is difficult t diagnosis. Chlamydia is second most common non-gonococcal infection
which tends to recur from time to time even upon complete treatment as the organism may hide in the urinary
tract and flare-up again in favorable conditions. As your urine was cloudy and painful discharge so your
doctor rightly suspected gonococcal infection at the first place and then treated your condition for
non-gonococcal causes through antibiotics. Now, you are experiencing discharge which could be recurrence of
non-gonococcal infection or if it is just a transparent discharge without pain then you can consider it
prostatic fluid ( if secretion is in excess then prostatitis may also be suspected). As we can not conduct any
test upon net therefore we would advice a consultation with an urologist for examination and urethral swab
test which can be microscopically examined to reach to a diagnosis. Until then you may avoid use of any
irritant substance like tight clothing, soaps etc., drink a lot of water may help reduce your problem. Hope
this helps. Do keep us posted in case of further doubts. Take care.
