Hi ladies, so yesterday i went to an out of hours GP with really bad abdominal pain that i have been having for last 3 days, i feel very sick and after food i cant seem to hold anything down, she did a urine test and said its a UTI and gave me some antibiotics called MacroBID 100mg prolonged-release capsules, i have to take 1 tab twice a day but my only problem is that i have not been getting any stinging or burning sensation down below and i was in hospital with same symptoms 2 days ago, they also did a urine sample and everything came back normal so im abit confused, i didnt have an UTI 2 days ago but all of the sudden i do and im not having any burning sensation when i pee, help please
