my right lower side where small and large intestines meet has been hurting for six months. dr. thought it was my endometriosis and took my female organs out. I am still in the same pain.
I know a few:
Unexplained weight loss
Keep needed to go to the toilet
A change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool for more than a couple of weeks
Rectal bleeding or blood in your stool
Persistent abdominal discomfort, such as cramps, gas or pain
Abdominal pain with a bowel movement
A feeling that your bowel doesn't empty completely
Weakness or fatigue
Unexplained weight loss
My husband was diagnosed 9/20/08 with advanced colon cancer with mets to liver.
He had been sick for 4 mos. exhibiting the signs people have listed in response to your question.
However, he also experienced severe chills, ran a moderate to high temperature and experienced nausea and vomiting.
He was encouraged to have a colonoscopy but refused until week of diagnosis.
Dont wait to long. He had a blockage in intestine and had 2 colostomies done as a result.
Also since his blood count has remained low they have been unable to inititate chemotherapy for palliative (comfort) reasons.
He has been one sick puppy. but we can be grateful that he is not experiencing any pain.
