ive noticed that a day or so after ive had sex with my boyfriend i have a burning pain whilst urinating, this stops when i drink about 2 litres of water for a couple of days then comes back.
i went to my gp and she prescribed me trimethoprim but it didnt work.
then today i felt as though i had thrush, like itchy internally and then excruciating pain passing urine and there was even blood present.
however, thats faded now after ive drank 2litres of water
what could this be?
