I have a combination of symptoms that have come and gone over the course of the afternoon and evening Dizziness all afternoon back pain on the left side this evening pain on left side when I breathed deeply earlier in the evening, but that has gone away sudden feeling of being hot that comes and goes - lasts a few minutes only pressure/pain in my sternum and diaphragm after eating that lasted maybe 5 minutes, and then went away sternum area still mildly uncomfortable unsure whether to seek medical attention this evening or wait till morning since symptoms come and go
