At times, I have had a irregular heartbeat - PVC , tonight - it begins with several irregular beats; and, can t get a full breath and nausea . Tonight, i felt in addition gutted feeling, like the pain you have after being punched in the stomach; About 45 minutes later I felt a slight pressure behind my jaw bone and ear, then I feel a swollen vein , not directly behind my ear, but directly under my ear lobe, close to the corner of my jaw. 155/107; not sure what is going on
