What else can this be? 6 months ago, my 62 year young twin went to have a shingles
shot. Her GP did routine blood tests and called at 8:30 at night to have her undergo phlubotomy. SHE HAS ABSOLUTELY NO SYMPTIOMS EXCEPT THE OXYGEN/diffusion - NO TIREDNESS,COUGHING,WHEEZING,SELLING IN ANKLES, CHEST PAIN,SHORTNESS OF BREATH.,Hemotologist did 1 1/2 months of testing and said not in blood, bone marrow, etc. Oxygen saturation was LOW, so placed on oxygen 24/7.
