urinary tract infection
"Started experiecing pain peeing and went for a quick dip test after blood in urine was strongly apparant. Prescribed Trimethoprim for a week and cleared it up very quickly however it came back. On the sixth day the doctor rang me urgently saying I needed to take these 4 times a day for a week.

No side effects at all. Possible constipation however this could be due to not wanting to eat/doing less exercise. No chest pains or anything and very quickly cleared up any remaining symptoms. Thank you Macrodantin!"
