Thank you for the query.
The reason of such symptoms may be intestines inflammation disease (Crohn`s disease, ulcerative colitis
), IBS, anal fissure
or even colon cancer
. There is a slight difference between severe constipation
and intestines obstruction.
You should not wait any more as the reason may be very serious. You should have abdominal ultrasound, fool blood work and colonoscopy.
Hope this will help.
