Hi,
By what you are describing there are a few possibilities -
- Reoccurance of rectal cancer - There might be some recurrence of the cancer. This can happen even after chemotherapy or radiation therapy.
- Irritable bowel syndrome - This is a bowel syndrome characterised by bloating, constipation, and diarrhea. Later can cause mucus and blood in stools.
- Polyps in the intestine can also cause the same symptoms.
To rule out all the above possibilities you need to contact your doctor as soon as possible. for a detailed examination and investigation. The fact that you are not having any pain in the stomach, fever or vomiting rules out a plain stomach infection.
