Thanks for posting your query.
With the available described symptoms, there appears to be possibility of left iliac fossa
pathology i.e. colonic growth or ulcer.
Presence of pain along with bleeding per rectum signify the diagnosis.
Bleeding from any where in body is an alarming sign and should be evaluated.
You should consult with internal medicine specialist/ general surgeon
and should go for thorough check up.
You should also go for complete blood count
, ultrasound imaging, colonoscopy
and x ray abdomen for better clarification.
Treatment depends on exact diagnosis.
Meanwhile, you should take hemostatic medication along with tramadol.
