once in a while i feel a sharp pain while urinating not on the tip of my penis but somewhere in the middle i have not noticed any white stuff or blood. what could be the cause.
Hi. Pain during micturition is a usual presentation of Urinary infection, but a sharp pain might suggest a small impacted stone in the urethra. Please get a routine urinalysis done, and in the meantime you can start a course of antibiotics (Ciprofloxacin 500 mg twice daily) and Chat Doctor.  Consult a urologist run the required tests.
