I ate salsa & chips at 10pm. I woke up at 2:30am with terrible pain in my chest & back between shoulder blades. I managed to get up, go to bathroom, but didn't do anything. Between then & 5:30 I ate 8 Tums. Pressure eased up some, but didn't quit. Since then I've had loose bm's at 7, 9:30 and 10:30. Still have pain, but mainly now on my back between shoulder blades. Pain is like I've couged so much I've bruised ribs, but I haven't coughed. I've belched, burped, and had gas, but still have pain.
