urinary tract infection
"When I started this medication everything was absolutely fine for the 1st two days, no side effects and I thought all was good, then on the 3rd day, (4 pills) I woke very early with the worst stomach pain and diarrhoea, I also felt nauseous and dizzy, I went to work as I was well aware of the side effects and tried to soldier on, I made it till about 2pm, another bout of diarrhoea followed by extreme nausea, I called the doctor and now have an appointment to swap antibiotics, still feeling slight signs of the side effects but it's only been 24 hours so I'm guessing it's still passing, fingers crossed the new stuff works better"
