I am a male, 28 years old, 5'9" and 60kgs. For a few days til now, i've been experiencing Heaviness and discomfort on the left side of my stomach and no trauma happened to me and no bowel problem... I'd already undergo ultrasound for the whole abdomen and 2D-Echo for the heart. But it seems everything is normal. what would be the problem? What will i do now?
