I do not know your past medical history. Severe abdominal pain
can be caused by many reasons but bleeding per rectum and urethra
is very alarming signs. If the previous cancer history and type of treatment were available to me it will be easier to address your issue. Any tumor in bladder if invade rectum may give similar symptoms but to make sure at least an abdominal ultrasound
to be done. Please try to contact your treating oncologist
. Take care.
