I'm 20 years old female and past seven days I'm feeling strong burning sensation down there, whenever I urinate. I always feel like I need to pee again after 10-15 min when I last urinated. I always have a burning sensation whenever I'm silently sitting or standing. I can't control my pee, it just suddenly comes with a strong urge to pee so I need to go to the washroom fast. My urine has also turned dark. I tried alkasol syrup but it was of no help.
