I've noticed when i eat my stomach feels uncomfortable (rumbles and feels gas/air is moving / escaping internally). going to toilet helps a little?

Feels things in guts: You may be describing visceral hyperalgesia--the heightened sense of gut distension & motility that many patients with irritable bowel syndrome experience, particularly at times of "mass movement." however, the same feeling may occur in response to partial obstruction (whether mechanical or functional). An abdominal obstruction series may reassure you, or may lead to additional studies.
