I spent the night in the ER for observation after suffering extreme nausea, dizziness, chest pains, neck pains and increased SOB. DRs did every heart test available and stated everything looked normal. Also took cxr and said that was clear and showed no abnormalities. A few hours after getting home, the symptoms flared up again. Now I'm wondering if something in my home is triggering my symptoms...Anyone else ever experience this. I was first told I had COPD, then changed to possible asthma. I'm so confused and no meds seem to help with the breathing issues.
