I experience intermittent severe stomach pain. This is generally in the middle, but can feel stabbing pains just below the right ribs and in the lower right side. My abdomen is tender to touch, and pressing it hurts. I also have irregular bowel movements - as well as painful bowel movements, random leg and arm pains, shortness of breath, regular coughing fits, a very weak immune system and chronic fatigue. These are to name a few. I have thought on multiple occasions that it could be cancer as it seems to be getting worse.
