HI and thanks for the question,
What you describe are signs of a urinary tract infection
for sure. Masturbation
could be a risk factor to collect germs on the skin and infect the immediate urethra. Prescribing Ciprofloxacine at the prescribed doses by your doctor was very appropriate. At times, it might take two to four days for clinical improvement to be observed.
Its advisable for you to drink lots of water now and fluids.
However, resistance to ciprofloxacin has been described in recent years, but its too early to think of it now. It could be somewhat appropriate to get a urethral swab, culture and antibiotic sensitivity tests as you continue with your treatment. If its sensitive to Ciprofloxacine, then you continue, if not, you continue with the sensitive drug. other organisms could also cause urethritis
like Chlamydiae and Trichomonas, with treatments that are quite different..
In situations where testing or cultures are not available, the WHO recommends use of Doxycycline, Metronidazole
and an analgesic for pain.
I suggest you visit your urologist
for prescription of these exams, or in case you don t get better.
Thanks and best regards,
