Does anyone get these? I have been getting them off and on for a while. It's like a flutter or pounding in my chest. Sometimes I feel weak, but I think that is just my anxiety kicking in. I have an appt tomorrow, but was wondering if anyone else has these and what their diagnosis was. I have googled it and apparently it can be anywhere from completely benign to very serious. I was very nervous after making the appt. because she kept saying "we really need to see you" over and over as she was checking the schedule. Gulp.
