First of all, as you may know Norfloxacin
is an antibiotic
and it should not be taken unless prescribed by your doctor.
It is given for a documented or suspected UTI
and should never be self prescribed, as it has some adverse effects and when taken injudiciously leads to increased resistance to antibiotics
in your body and it would not work for you when you would really need one.
Please see a general surgeon
for your complaints.
Hope my answer was useful to you.
