Abdominal pain - lower pain, mainly left side. Worse first thing in the morning and during the evening
Bloating and wind - clothes feel tight and awful wind, belching and the other especially after food.
Pain under left rib - trapped wind and burning sensation
Variable BM - intermittent constipation, flat stools, feeling that I haven't emptied bowel properly, diarrhea mostly in the morning.
Back pain - lower back, coccyx spreading to buttocks.

I have had good blood test results and a perfect abdominal/pelvic scan. I have no blood or mucus in stools, no weight loss, insomnia or loss of appetite. I do however, have a great anxiety that this is something more - that the doctors have not suggested the proper tests like colonoscopy etc. My doctor has diagnosed IBS but I keep thinking it is bowel cancer! I am 37 years old with no family history of cancer but plenty of family history of anxiety!!

What shall I do?
