I've suffered from shortness of breath for the past 7 years, which just came and went. However, it has been getting worse in the last 5 months or so and I suffer from a persistent shortness of breath, sometimes with slight palpitations. My lung function test, chest x ray, abdominal scan, echocardiogram and full blood countcame back normal. I also did a tuberculin test which showed a result of 12mm but which my doctor said we could ignore as I had been diagnosed with tuberculosis 20 years ago, took the necessary medication and was cleared of the disease. During my periods of shortness of breath, my stomach seems bloated a bit and I need to belch out air. I've seen a physician who said I probably have a hiatus hernia, however the medication did not help. I then saw a gastro enterologist who put me on a high fibre diet since he said my large intestine seemed to be having a lot of air in it. I've been on the diet a week, but no marked improvement. I used to sneeze a lot prior to developing this shortness of breath and probably had hay fever. However, none of the hay fever symptoms appear now, except when I smell strong perfumes or vehicle fumes, which make me slightly shot of breath. I'm 32 years. Could you please help?
