for UTI what you could do is, have plenty of water atleast about 4 litres of water a day so that you urinate often. by this way, the bacteria will get washed away.
drink cranberry juice or have cranberries.
there are syrups available called renal alkalisers take that 5 ml in 100 ml water 3 times a day.
along with all this you may require antibiotics and antipyretic and analgesic tablet for symptomatic relief.
if first line antibiotics don't work, get your urine culture and sensitivity done because the bacteria could be a resistant strain. so it will help in identifying specific antibiotics.
consult a physician or a gynaecologist.
