Hi,
You got pain on the left side of abdomen since 2 months. You had severe diarrhea, weight loss.
Colonoscopy, C.T. scan, stool examination were all normal.
You are a smoker for 20 years; it may have caused ischemia of the intestines, due to
atherosclerosis.
The other reasons for pain in the left side of abdomen could be
urinary tract infection, stone in the ureter or medulla of kidney, hernia. As you have diarrhea it could be the infection in the intestines, and rarely due to anxiety. The reason for no cure of diarrhea may be Diabetes, or H.I.V., or
tuberculosis of the intestines.
It may be the intolerance to foods like milk, milk products, wheat, and barley. So avoid these things and spices, junk foods and oily foods.
You are in habit of taking alcohol and left it now. You were taking opiates and left them since 8 months. These may not be related. You got depression and taking medicines, one of the medicines may cause irritation of the stomach, and causing pain.

furazolidone,
metronidazole, and dicyclomine hydrochloride for temporary relief, until the diagnosis is established.
