HIT hanks for posting your query to Chat Doctor .  Yes Abdominal Aneurysm can cause these symptoms, but it is slightly less common in occurrence while there are other conditions which can cause the problems mentioned by you and which are more common in prevalence than Abdominal Aneurysm.  Other possible causes are Disc Prolapse, Kidney stones, Inguinal Hernia.  I advise you get MRI Lumbar spine and urine routine tests done and revert. Any clarifications feel free to ask. Happy to answer. Regards.
