Piggy, wat did u drink when u eat the bread? sugary drinks? for me, i realised that after a certain timing in the nite, after drinking sugary drinks confirm will itch down there. thats y either after i drink the sugary drink must drink more plain water, if not dun drink the sugary drink at all. the bacteria can come and go, not necessary wait until ur antibiotic finish. btw, too much of antibiotics will cause u to have low resistance to bacteria and more dependent to the medications. low dosage may not be able to clear the bacteria in future if keep on taking the med.
