A few nights ago, a couple hours after dinner, my stomach started to feel uneasy. I got gassy; mostly burping. I felt very uncomfortable and gassy when I went to bed. I woke up in the middle of the night with very bad diarrhea. After my first trip to the bathroom, I had to go right back in and vomited a whole bunch. I woke up about six more times through the night with very liquid and acidic diarrhea, but no more vomiting. The next day I felt weak, but slowly recovered through the day. I had quite a bit of gas, mostly very foul smelling flatulence, but no diarrhea or vomiting. The following day I felt better and ate normal again. I passed stool twice, both times it was soft and very green in color. That night I went through the same series of events, only without vomiting. My stomach got uncomfortable and I had bad gas. I then had awful diarrhea several times through the night. Very liquid and acidic again. I experience very painful butt burn. There is no blood in the diarrhea. I have had a cough for the last couple days of it. Also, a stinging in my left arm, right above and around the elbow. I am a 29 year old male who is normally healthy, other than allergies. Thank you.
