This is wierd. Has anybody has the symptoms? After eating I get short of breath and have irregular heartbeats, like it's skipping a beat, then I get dizzy and then those sharp pains right under my left rib. All of a sudden I'm fine, and then beat, beat, kathunk, beat, beat kathunk. Feels like my heart is in my throat and I go ugh and then my back shoulder blades start hurting. I get a real full feeling from my breasts to my neck (sort of stuffed feeling). This drives me nuts!!! I've had heart checked out (he just told me to loose weight!!!) Is this part of IBS???
