I’m a 27 year old male. Long story short about 3 months ago I had an extreme episode of abdominal pain and gas after drinking one night. I started cleaning up diet and It eventually went away but came back again over Christmas were I was bed ridden with gas pain and nausea. Since Christmas I’ve noticed I’m having flatter stools and stool more on the yellow shade. Also since Christmas I’ve had the worst of gas of my life and mild constant nausea. The most persistent symptoms are the flatter stools and constant nausea. The nausea comes in stronger after eating. 

My stools have no blood, no black or tarry or mucus. They are usually yellow tint and I’m having bad gas, constant nausea, and flatter stools. 

Over Christmas I went to the urgent care and they did a ultrasound on gallbladder and edge of liver and found nothing. They also did a complete blood count and metabolic blood count and there were no read flags. 

Should I be worried about cancer or something bad? Can flat stools come from an irritated and tighter butt hole? I will also note I am regular and poop around same time every morning.
