Has anyone experienced low pulse ox (93-95%) and high MCH over 33 before treatment?
I know most people don't have the kit, but after having mine tested multiple times a couple of years ago whilst having 2 operations in hospital it was consistently low while at rest, then would go to 95-97 if I breathed heavily for a minute so I could get enough in if I needed to.
Since I started with the neurological symptoms of b12 deficiency I wondered if this was still the case and if it might be related to the "sighs" reported as pa symptoms so I bought a machine (only £14) and am still 93-95 at rest watching tv, with no sighs.
My GP is focussing on the level as being symptomatic of some underlying heart defect as I seem to know a lot more about b12 than she does, but is negotiating with the practice to trial cobalamin injections to see if that is the cause of the Neuro & fatigue. I'll update once I start the trial and will monitor the pulse ox.
