<s>[INST] I was just told I hav to see a specialist for hemorrhagic cystitis, ive had 2 sudden bladder infections. lost a lot of blood and had a lot of clots - for hours. I had no warning with either. came on so fast and we live over an hour from a hospital. worst pain of my life. what can I expect. very nervous!!!! [/INST] HI   Thanks for posting your query .   Hemorrhagic cystitis occurs due to infection of urine , stones in bladder or due to side effect of certain drugs . Whatever the cause is it's easily treatable .    But you need to get tested to see what is causing it . I advise you to get Urine Culture sensitivity , Ultrasound Abdomen Pelvis scan done and revert back . Any clarifications or Queries feel free to ask. Happy to help you. Regards </s>
