I am a 33 year old Male, very healthy, 6'2", 175lbs normally. About a month ago, after a vacation to Galveston Tx, I started experienceing chest and abdominal discomfort. It started with chest "discomfort", I can't say pain, and lightheadness that I eventually went in for an EKG on. They found nothing and told me to forget about it. The following week I noticed the chest discomfort had subsided a lot but I was not having bowel movements although it felt like I should and I totally lost my appetite and craving for my morning coffee or soda. A week later that seamed to pass and I got a little of my appetite back. I was told to start taking Metamucil to restore my bowel movements and it's helped a little, but if I don't take it, I don't go. That was followed by the back of my neck hurting and that felt like a burning sensation or like my muscles were just overused, it was a constant ache or burn. I also had bloodshot eyes for a few days. Both those symptons have now gone so I don't know if they were related or not. I still have the occasional chest discomfort that feels more muscle oriented than anything, that is sometimes occompanied with a shortness of breath, and light headness. When I eat, I get full after only a few bites and it feels like the food is stuck at the top of my stomach. I belch and yawn a lot. I've also lost about 8lbs without trying. Maybe this is due to my lack of eating??? My chest usually feels better if I lay on my stomach. It's going on 4 weeks now and I'm normally a really healthy guy. It's starting to make me worry what's up. Does this sound like a bug I could have caught, or muscle strain, or could it be intestional related?
