I ve been experiencing neck & throat discomfort for some time now - at least 3 occurences/month. -feels like there is a splinter and it won t go away, even when I try to swallow . -have been seen by 2-ENTs both of whom dropped an NG tube, but neither found anything. I was also seen by a cardiologist, as I was beginning to think maybe the discomfort was cardiac-related. After an echocardiogram and extensive bloodwork - nothing was found. It continues to be ongoing. Any ideas, please?
