The other week I posted about my DH and his UTI. He never did end up going back to the doctors after the clots thing (it never happened again and he's been fine since) but he's just gone down there now with another sample that they asked him to take in 'to make sure it was a UTI.' I've had several over the years and have never had to take a follow up sample in just to make sure that's what it was. Is this normal practise? I'm a bit concerned that they suspect something else.
