What causes a sudden intake of breath?
A couple of years ago I started to suffer with a sudden sharp intake of breath. Basically I would be breathing normally and then suddenly take an uncontrolled sharp deep breath. I asked my cardiologist about this but he just said it was nothing to worry about. However it does seem to have got worse over time and sometimes when it's a very deep breath I get a dull pain in my upper left back. Has anyone else experienced this and is it a cause for concern.
For reference, my history is, bypass surgery 24 years ago, mild heart attack 7 years ago. I also had catheter ablation 4 months ago to cure AF.
