Hello, thanks for using HCM.
there is a vast number of causes of left abdominal pain
. A negative colonoscopy and MRI is comforting as they exclude anatomical pathologies including cancer which is your worry. Cancer is associated with altered general condition, progressive weight loss, loss of appetite, weakness, sometimes low grade fevers; in the case of gut cancer, bloody stools, diarrhea or constipation
, abdominal pain etc. The causes of such pain in the left side of the abdomen include diverticulitis
, irritable bowel syndrome
, constipation, inflammatory bowel diseases, intestinal polyps, spleen enlargement, typhoid fever
, muscle tension etc which have been excluded from the colonoscopy and MRI done ( apart from irritable bowel syndrome, typhoid and muscle tension).
Irritable bowel syndrome presents with crampy lower abdominal pains, diarrhoea or constipation, bloatedness and a feeling of not haven completely pased out stool. Typhoid could present with pains and constipation, while muscle tension will present mostly with just pains. Since it is your left side that is dominant, probably you have muscle tension.
Further test could be stool culture and redo MRI and colonoscopy.
