For the past week, I have been experiencing extreme fatigue, diarrhea and stomach pains. I can sleep for almost 24hours, wake up, and still be unbelievably tired, almost to the point of fainting. Along with my fatigure, when I am awake, I have a constant stomache. I end up having to sparatically use the toilet without much warning. In terms of my stool, it looks very flaky in nature, never anything solid and always a light light brown colour. And when I pass gas, the smell is very unpleasant. My stomach hurts in two places. There is a constant pain in the lower abdomen that feels a mixture of pressure, constipation and sometimes as if there is something moving in my stomach, creating that sense of pressure. Than everytime I eat, but only when I eat, I feel sharp pains just below my sternum. But this only happens when I am eating.
I'm a 20 year old, regularly healthy and fit male. I have recently (For the past month) began working nights at my job. This means from 9:30pm to 6:30 in the morning. My eating pattern usually begins at 8pm at night, being my first meal that day. Than I eat again around 1:30am on my lunch. I was drinking coffee and enegry drinks at first to help keep myself awake during the late hours, but since the cramps and fatigue came, I've discontinued that.
Please give me any information you have on why I'm suddenly experiencing these symptoms, and potentially some options on what they may be. Any help is appreciated, thanks. :)
