since saturday (today mon) first day was severe heartburn with nausea and elephant on chest feeling. Sun started having pains at bottom of sternum at top of stomach. Today had pains at bottom of sternum, with high blood pressure newest reading being 163/116 81 heart rate and pressure like elephant on chest. Along with finding a lump at bottom of sternum right in the middle with little bit of pain and the lump doesn't move. No heartburn today though. The pain at sternum isn't the lump its a feeling of severe hunger intensified massivly. I don't have insurance but all this together is making me scared. So any and all answers will be appreciated.
