I have heard that some people with CFS suffer hyperventilation, i.e. over breathing, but I'm not sure that is what my problem is. I'm not actually sure what is wrong with my breathing. I know that I am often aware of my breathing and that it is frequently uncomfortable. I feel like I am not getting enough oxygen. At first I thought it was hyperventilation as I did the test where you measure your control pause, and my control pause was really short indicating that I was hyperventilating. However, when I then did breathing exercised to reduce the amount I was breathing - I seemed to get worse! So I'm wondering - what other breathing problems do CFSers suffer? I have gone to the doctor about this and she says that my breathing seems fine to her, but yet it is causing me a lot of distress. I just don't feel like I am getting enough air, and sometimes I find it challenging to breathe at all. Could I be under-breathing? And what can I do to help this? Sorry if this post isn't clear. Just say if I haven't explained myself properly and I'll have another go lol!
