I am experiencing chest pain or discomfort when i breathe deep. i also have severe feelings of indigestion. this started after painful vomiting twice. sternum feels heavy and almost as if air is trapped. right pectoral is now twitching rapidly.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor. Alternatively, you could watch and wait. It is likely that the symptoms will subside in a few days. If you still have these symptoms, ten days from now, you should see a doctor. If you are overweight, if would help to lose weight
