I only ask because I have a severe breathing issue that is yet to be satisfactorily diagnosed. I've been told I just have a 'breathing dysfunction' but that suggests over (or under) breathing. Which I'm clearly not.
But it's gradually getting worse and has been for almost 3 years. I also suffer with CFS/ME and, while I realise this is a strange place to ask, I know that it will still cause severe respiratory distress if those muscles aren't working properly.
If you do, what does it feel like to you? I often feel like I'm trying to inhale whilst a dead weight is sitting on my chest and pressing against my sides. Lying down is much worse and I find I manage little exercise without being totally out of breath, I was gasping this morning after just washing my face. I'm 39. I've had the whole gamut of lung function tests and my lungs are fine. But there's clearly a muscular issue for me, it's just convincing my doctors that that's the case.
