I have this same problem as of tonight. Spasms directly behind slightly below the sternum. No pain just odd and uncomfortable. I have a history of anxiety problems which I take pills for and digestive problems (Lactose intolerance, acid reflux, constant runny stool). Started after eating some pizza covered in crushed red pepper. Could be relate to Lactose problems or the spicy part of that meal. Either way anxiety and foods seem to be a common theme amongst this problem.

I have developed the same thing in the last week, a rippling, vibrating and sometimes gripping feeling right in the sternum area. I had my gall bladder removed about 18 months ago, and am wondering if that has any connection to this. My gut feeling is that it is more than likely related to stress or some muscle sapsm thing! However, it is very unsettling when it happens. It can happen when I am relaxing and also it can come on after a cough, sneeze or laughter, I want it stop!!! this started after a stressful time at work, perhaps....perhaps...
Anyway, very good to hear of other people's stories, it is somewhat comforting.

I have had overwhelming stress within the last couple of years and I've been experiencing these symptoms for well over a year. It seems to be getting worse. I have had an upper GI tract exam, EKG, x-ray, Nexium, Aciphex, blood work found H Pylori positive. I am so discouraged and the fact that no doctor can tell me what is wrong stresses me out even more. I've described this spasm/ fluttering, feeling to several doctors who all look at me like I need to be admitted to a mental hospital! Mine started in the lower right abdomen area but lately, it's moved to the left section just under my left breast and it does feel like a babe is in there but I know that's not the case.

I'm so glad that others have shared their experiences. I really need to know what's going on with me so that I can feel better. Please continue to post.

Thanks
