Sorry for what seems a rather complicated and in some ways trivial first main question. I have had a look at some, just some, of the may posts on fatigue. I am getting progressive episodes of feeling that I am not breathing enough/sighing/yawning. This is associated with lower O2 SATs (mean 94% sedentary activity mean 90% resting with lows of 84%) this improves with exercise (SATs go up) or after some rest/sleep. I have raised this with my brothers (who are doctors) and they know a good bit about my co-morbidities. What I was wondering here is if anyone thinks this sounds like fatigue or whether we should be looking wider. Apart form raise ALC I have quite sound bloods staged at A Binet and probably 0 on US system. So the Haematological consultant said there was no Haematological reason for this. That is as maybe but it does have an increasingly severe negative impact on my quality of life.
