Extreme Abdominal Pain and Nausea

Im only asking for advice since we're not doctors but ive been having this exteme pain in my abdomen all around like it spreads but fades off and on all day but last minimum of 2 hours, and i have been using the restroom alot more often than normal (around every 30 minutes) as well as ive been very fatigue, nauseous, and unable to eat any kind of food like the nausea causes such discomfort i cant chew it. I've also been having extreme rib pain that worsens when taking deep breaths, coughing, laughing, and moving a limb. anyone know what it could be? or whether i should go to a professional to see what is the problem?
