Please help! I am 51 years old. I have a feeling of suffocation. It started suddenly with shortness of breath and a feeling I am suffocating My chest becomes very heavy and I feel extremely dizzy. At a point, I could not stand up and walk for days. When I stand up. I am not balanced. My head becomes very heavy. When I lie down I feel better so it is like I am always lying down which is not good. My activity level is drastically down.I fear falling or collapsing so I don't get up when I am alone.The suffocating feeling comes mostly when I stand up to walk. It is like my breath has ceased and I feel a surge of air or gas welling up and blocking my chest. I react by hitting my chest and gasping for breath. It is scary.I feel constantly weak and I bulge (burp) a lot.Initially, I thought it was stroke.
Its been on for almost one year. I don't smoke or drink. I have been to so many doctors and done a lot of blood tests, ex-rays, Brain Scan, heart test but the doctors say all tests are perfect.I have crossed checked the interpretation of the medical test results with different doctors to be sure. I have done ECG, Fasting Blood sugar, kidney, liver tests,you name it. Some doctors say it is Anxiety syndrome, some say it is Hyperventilation, some say it is due to imbalance of oxygen breathed in and carbon dioxide breathed out.
Any idea what l am going through and recommendations for treatment will be helpful. I have stopped going to work because I cannot walk well and I am always feeling dizzy and feel I am suffocating.
