53 year old male recently diagnosed with type 2 diabetes. Good glucose with two oral meds, controlled diet, exercise. Experienced rapid, significant weight loss-40 pounds in about 3 weeks (240 to 210). Low carb diet. Not injecting insulin. Upon executing abdominal exercises (leg lifts, crunches) noticed bulge about 3 wide and 5 long, from upper right side of abs toward pubic bone. Looks scary. Concerned could be AAA? No pain. Lump is soft and movable. Looks like a cucumber or sausage under my skin. Only appears under stress. Plays trumpet as a hobby-requires deep, lower ab distention upon inhaling (breathing from the diaphragm). No pain. Normal digestion. No nausea, etcetera. Most likely a hernia? No clue I m an accountant. Thanks.
