A little below left rib there is gurgling grumbling feeling & sometimes sound. It moves down sometimes as well. Has been going on for weeks. Is it gas?

Possibly... Left re under rib anatomically corresponds with " splenic flexure of the colon" or " loop of gut " where gas gets easily entrapped before it moves down to " sigmoid" and rectum.It is very common area of complaints as cramping, bloating, noises..young person as you unlikely have diverticula. Much of gurgling depend on diet. Avoid processed food, consume fresh produce, Yogurt, kefir, water. Exercise.
